HPZ AND HSR HYDRONIC PANEL WIRING DIAGRAMS

NOTE: If more than 8 total zones are needed, multiple HPZC105 (5 zone) or HPZC106 (6 zone) panels can be used. The wiring is the same as shown here except there are additional zone connections. One of the zones is used for panel communication.

NOTE: If more than 7 total zones are needed, multiple HPZC105 (5 zone) or HPZC106 (6 zone) panels can be used. The wiring is the same as shown here except there are additional zone connections. Two of the zones are used for panel communication.

NOTE: This diagram is specific to how Taco valves can wire to an HPZC zone valve panel. All zones other than an optional Domestic Hot Water zone are wired the same. See other diagrams in this file for options on pump and line voltage wiring, using multiple panels for systems over 6 zones, DHW priority, etc.
