Wiring Thermostats

Run wire from the Thermostat 1, 2, 3 terminals to the corresponding terminals on any one of the EnviraCom bus terminal sets. More than one thermostat or other communicating device can be connected to a bus terminal. See Fig. 3.

Wiring Equipment

CONVENTIONAL EQUIPMENT
Connect the first stage heat to W1/E, second stage heat to W2, and third stage heat to W3/Aux. Wire first stage cooling to Y1, and second stage cooling to Y2. See Fig. 3.
If separate HVAC equipment transformers are used for the heating and cooling systems, such as for an oil furnace, wire the heating transformer hot wire to Rh and the cooling transformer hot wire to Rc. Locate the Rh/Rc jumper above the equipment terminals and remove the jumper to expose the two pins.

HEAT PUMP EQUIPMENT

Connect the Y1 terminal to the first stage compressor, and the Y2 terminal to the second stage compressor. W3/Aux is the auxiliary heat and W1/E is the emergency heat. If emergency heat and auxiliary heat use the same piece of equipment, place a jumper from W3/Aux to W1/E and wire it to the resistive heat equipment. See Fig. 4 and 5. See Fig. 6 and 7 for two- stage heat pump equipment.


Fig. 3. Conventional equipment wiring diagram.

Fig. 10. Wiring two RRD dampers in parallel.

MARD Dampers or Dampers using ML6161 Motor Actuator

Wire the MARD Damper or other damper using the ML6161 Actuator to the panel as shown in Fig. 11. These floating control actuators are controlled as two-position devices on the W8835 panel. The ML6161 motor causes the damper LED to illuminate green constantly. To restore damper position indication, mount end switch 201052B onto the ML6161.

Transformer

Wire the transformers to the panel (see Fig. 12). One 40 VA, 24 Vac transformer is required to operate the panel and up to five ARD or ZD dampers. The transformer is connected to terminals R and C. The auxiliary transformer is required if up to ten dampers are connected to the panel. It is wired to terminals T1 and T2. If more than five ARD or ZD dampers are required for one zone of if more than ten ARD or ZD dampers are required for the W8835, use the Slave Damper Control Relay (SDCR). Locate the XFRM jumper shown in Fig. 12. These jumpers are shipped in the open, disconnected position. This is the correct position when two transformers are used. When using one transformer to power the panel, place the jumpers in the closed position. Do this by removing the jumpers and installing them so they cover both of their respective pins. If preferred, one 75 VA transformer may be used on this panel instead of two 40 VA. If this is done, leave the jumpers in the open, disconnected position and install a jumper between R and T1. Wire the transformer to R and C.

CAUTION

Equipment Damage Hazard. Incorrect transformer wiring can damage panel.
Wire transformers in phase when one transformer is wired to R and C and the auxiliary transformer is wired to T1 and T2.

OPERATION

Sequence of Operation

When there is no call for heat, cool or fan, the board is in the idle mode, indicated with no system LEDs illuminated, see Table 3. Damper LEDs are green to indicate open. On a call for heat, cool, or fan, the calling zone damper stays open and the damper LED remains illuminated; the other zone dampers close and corresponding damper LEDs do not illuminate.
The W8835 panel energizes the HVAC equipment and conditioned air is delivered to the calling zone. The heat LED (red), cool LED (green), or fan LED (green) illuminates to indicate equipment operation.
The fan LED illuminates only on a call for fan; it does not illuminate during a call for heat or cool. When the heat/cool call is satisfied, the system enters the Purge mode, indicated by the Purge LED (yellow). Damper positions either remain in the same positions as at the end of the call for heat or cool (default) or open, depending on the position of DIP switch 6. After purge, all dampers return to the Open position.

COM LED Operation
The green COM LED flickers as the W8835 communicates with the other EnviraCom devices:
LED blinks rapidly—indicates device is currently transmitting information on the communications bus.
LED blinks once—indicates device received and acknowledged a message.
LED on constantly— indicates panel failure. Replace panel.
LED off constantly—indicates a wiring problem.

b An LED change precedes the corresponding relay change by as much as six seconds.

Purge Mode

At the end of every call for heat or cool, the panel enters a Purge mode. DIP 4 configures the panel to purge for two (default) or three and one-half minutes. DIP switch 5 configures the panel or the HVAC equipment to operate the fan during purge. The Purge LED lights to signal that the system is in the Purge mode. Pressing the purge override button overrides the Purge mode. Unless there is a new call for heat or cool during the Purge mode, all dampers are moved to the Open position at the end of purge. DIP switch 6 is used if it desired to open all dampers during the Purge mode.

Individual Zone Fan Control

When all zones are satisfied, the fan switch of each thermostat controls the fan operation for that zone. When the fan setting is “ On”, the fan is energized, the fan LED illuminates and the dampers close to zones where the fan setting is “Auto”. If there is a call for heat or cool during this time, the fan mode ceases, and the heat or cool call is honored. When the zone calling is satisfied, and Purge mode has ended, the fan call resumes.

Single and Multi-Stage Conventional Heat Operation

The panel can control up to three stages of heating and two stages of cooling based on thermostat demand. Set DIP switches 1 and 2 for 1, 2 or 3 stages of heat. Set DIP switch 7 for one or two stages of cooling.

Wire the reversing valve to the O/B equipment terminal. DIP switch 9 configures this terminal to operate as an O (cool) or B (heat) changeover terminal.

Hydronic Heat Operation

The W8835 is a forced air panel. However, it can be wired to control hydronic valves as shown in figure 13. To control valves or circulators on a hydronic panel, see figure 14.

Thermostat Operation

Dual Fuel Equipment

The W8835 can operate Dual fuel equipment when used with an external fossil fuel kit. Locate the thermostat on the fossil fuel kit instructions and wire the W8835 equipment terminals there.

Emergency Heat Control

Emergency heat is defined as using an auxiliary heat source without using the heat pump. The W8835 energizes the E terminal on a call for emergency heat. The thermostat system switch is set to Em Heat to engage this function. When active, any zone calling for heat uses Emergency Heat, not the compressor. The panel energizes W3 as auxiliary heat with the Y1 and Y2 for compressor control in when not in emergency heat.

Manual and Automatic Changeover Operation

Each of the thermostats can be set for manual or automatic changeover. If one or more thermostats call for cooling while one or more thermostats call for heating, the panel attempts to satisfy the greatest demand first. Then, based on the relative demand for heating and cooling, the panel intelligently switches between heating and cooling. The system attempts to satisfy both the heating and cooling demands, and does not lock out one demand in favor of the other.

Discovery

Discovery is an automatic system configuration program where the panel configures itself to operate with controls connected to the EnviraCom bus. The panel enters Discovery when the Discovery button on the panel is pressed.

Rebooting Microprocessor

To reset the microprocessor, press and release the Boot button. The system reboots and enters the Purge mode.

EnviraCom Furnace

For furnaces with EnviraCom communications built in, configure the panel as shown below. In this case, no conventional equipment wiring is necessary because the W8835 uses the 3-wire EnviraCom bus to control the HVAC equipment. In these installations, the panel is powered from the HVAC equipment via the 1, 2, 3 wires. Because of this, the transformer R and C terminals on the W8835 are not used. Instead, leave the XFMR jumpers in their default disconnected position and wire the transformer to T1 and T2.

Table 9. Furnace Type Configuration

Type of EquipmentDIP 3
ConventionalOn (Up)
EnviraComOff (Down)
Humidity, De-humidity and Ventilation Control

The panel can control humidity, de-humidity, and ventilation by receiving messages from the VisionPRO® IAQ thermostat. The thermostat designated as zone 1 will have control of these functions. Configure this thermostat as found in the installation instructions for the thermostat. The humidity, de-humidity, and ventilation terminals are all dry- contact terminals; the relay contacts close when active. So devices that need dry contact control like a ventilator can be wired directly to the VENT terminals, or a steam humidifier can be wired directly to the HUM terminals. Devices that need to be powered like a ventilation damper or some models of evaporative humidifiers are wired using the VENT or HUM terminals wired through the R terminal as shown in Fig. 3.
If using a Honeywell TrueSteam humidifier, configure the zone one VisionPRO IAQ thermostat installer setup #374 to “3”, and wire the TrueSteam GF terminal to the HVAC fan terminal, and wire the TrueSteam GT terminal to the G on the W8835.

NOTE: When controlling a steam humidifier, set all thermo- stats to HEAT. Do not set thermostats to AUTO. This prevents the panel from humidifying on zone 1, when another zone is calling for cooling. Alternatively, set zone 1 thermostat Installer Setup 374 to “2” to allow humidification only during calls for heat.

Discharge Air Temperature Sensor DATS

The C7835A1009 Discharge Air Temperature Sensor (included in the Y8835 kits) is a supply-duct-mounted temperature sensor probe used to control capacity and prevent high plenum temperatures or coil-icing. The sensor is wired to the EnviraCom bus using three wires. When a high or low limit is reached, the panel shuts off the equipment and keeps the fan operating for a minimum of two and one-half minutes. After this time, and any applicable minimum-off times imposed by the HVAC equipment. It re-energizes the equipment when the discharge air has recovered by ten degrees. When the high or low limit is exceeded, the Heat (red) or Cool (green) LED on the DATS flashes. When the DATS is in a limit condition, the Heat, Cool and Purge LEDs on the W8835 panel continue to operate as if the DATS were not turning the equipment off. The high and low limit is set on the DATS. The high temperature limit is set from 110°F to 160°F with a small screwdriver or using fingers and the low limit is set at 40°F or 48°F degrees with a jumper.

Circuit Breaker Protection

A built-in thermal circuit breaker protects the EnviraZone panel against shorts in the damper wiring and EnviraCom bus. It does not protect against shorts in the HVAC equipment wiring into the panel.

When the circuit breaker is tripped, none of the LEDs illuminate and the yellow rectangular component located bottom center on the panel is hot to touch.

  • Remove power to the panel for at least five minutes to allow the circuit breaker to cool off and reset.
  • To eliminate the short, verify the dampers and transformer  wiring.
Fan On In Heat

The system blower can be set to come on with a call for heat as required for hydro-air or electric heat systems. Set the blower function using DIP switch 8. When configured for heat pump, this DIP switch is not used.

Adding Additional Zones

Connect one W8703 to the EnviraCom bus to expand the system up to six zones or connect two W8703 to control up to nine zones:

  • Wire the first three zone dampers and thermostats to the W8835 Envirazone Panel.
  • Wire the additional dampers to the W8703 Panel.
  • Set the DIP switches on the W8703 to correspond to the zones being See W8703 Installation Instructions.
  • Wire terminals 1, 2, and 3 from the additional thermostats to terminals 1, 2, and 3 on any of the Panel.
