DocumentDocumentZP6 Six Zone Forced Air Zoning System The ZP6 is a residential and light commercial forced air zone control system that allows a single HVAC unit to have up to six separate zones. The system can be expanded to as many as 12 zones by adding 3-zone expansion modules. Intuitive firmware allows the panel to be used with single stage, multi-stage, heat pump and dual fuel equipment having up to 3 stages of heating and 2 stages of cooling. Standard heat / cool or heat pump thermostats can be used with the ZP6 along with a choice of two or three-wire zone dampers. The ZP6 comes ZP6 and all ZPA-DTS 1. Mount the ZPA-DTS Discharge Temperature Sensor in the supply trunk. Mount the sensor out of the line of sight of the heat exchanger and cooling coils whenever possible and before any zone dampers. The ZPA-DTS sensor has a resistance value of 10,000 Ohms @ 77° F. ZPA-OTS (For dual fuel applications) 1. Mount the ZPA-OTS Outdoor Temperature Sensor inside the outdoor unit where it will not be directly exposed to sunlight, water, snow or ice. The ZPA-OTS sensor has a resistance value of 10,000 Ohms @ 77° F. The 24 VAC equipment common does not wire to the ZP6 panel. BLINKS when outdoor temperature sensor is connected and when panel goes out on high or low balance point. High Limit (ZPA-DTS Sensor) - Adjustable from 100° to 175° F. High limit setpoint should be below safety limit setpoint of heating system. When limit is reached, fan continues to run but equipment is shut off or down-staged to prevent overheating. Low Limit (ZPA-DTS) - Adjustable from 40° to 58° F. Used to prevent coil from freezing. Allows fan to run but shuts off or down-stages equipment while activating a time delay to prevent short cycling. Low BP (ZPA-OTS) - Used to set the low balance point to prevent heat pump operation when outdoor temperature falls below setpoint. Adjustable from 0° to 50° F. High BP (ZPA-OTS) - Used to set the high balance point to prevent fossil fuel heat operation when outdoor temperature rises above setpooint. Adjustable from 55° - 70° F.

Dual Fuel Low Balance Point Whenever the outdoor temperature drops below the low balance point setting and the system changes over from heat pump to the auxiliary heat source (gas or oil), auxiliary heat will remain on until the call is satisfied regardless if the outdoor temperature rises above the low balance point during the heating call. USING THE ZP6 WITH HEAT PUMPS AND DUAL FUEL EQUIPMENT REVERSING VALVE: Make sure that the heat pump thermostats and ZP6 reversing valve system switch are configured in the same mode. O = Reversing valve energized on a call for cooling B = Reversing valve energized on a call for heating When the reversing valve is energized on a call for heating (B) or cooling (O), the O/B LED will be ON, The reversing valve will remain energized until an opposite call takes place. HEAT PUMP AUXILIARY HEAT WIRING: The zone thermostat auxiliary heat terminals are marked W3/AUX. The HVAC System auxiliary heat terminal is marked W3/AUX/EH. (See Typical Thermostat Wiring Diagrams) THERMOSTAT CONTROL OF AUXILIARY HEAT: When a zone thermostat calls for auxiliary heat in standard heat pump mode, the auxiliary heat cycles and the heat pump compressor will be on at the same time. When a zone thermostat calls for auxiliary heat in dual fuel (fossil fuel) mode, the heat pump compressor is locked out and auxiliary heat (fossil fuel) becomes first stage until the heating call is satisfied. Heat pump thermostats should always be configured for electric backup regardless of what type of backup heat is present. BALANCE POINT CONTROL: Low Balance Point When a zone thermostat calls for first stage heat in dual fuel (fossil fuel) mode and the outdoor temperature is below the selected low balance point setting, the heat pump compressor is locked out and auxiliary heat (fossil fuel) replaces heat pump operation. This feature does not apply for standard heat pump operation. High Balance Point When a zone thermostat calls for auxiliary heat in standard heat pump mode and the outdoor temperature is above the selected high balance point setting, the auxiliary heat will be locked out. This feature does not apply for dual fuel (fossil fuel) operation. EMERGENCY HEAT: In the event of a heat pump failure, only one zone thermostat needs to be placed in the Emergency Heat mode. The ZP6 panel remembers the zone thermostat set in the Emergency Heat mode and treats all calls for heating from any zone as an emergency heat call. The EMHT LED will be ON to signify that an emergency heat call has taken place. To reset the system back to standard heat pump operation, take the zone thermostat out of the Emergency Heat mode. On the next call for heating the EMHT LED will be OFF and the panel will resume normal heat pump operation. PANEL FUSES: 4 AMP PC Board Fuse The 4 AMP PC board fuse is designed to protect the ZP6 panel, zone thermostats and zone dampers from a 24 Volt short. Replacement fuse should not exceed 4 AMPS. 2 AMP System Fuses The two, RC and RH 2 AMP system fuses are designed to protect the ZP6 panel from a 24 Volt HVAC equipment short. A 2 AMP spare fuse is located on the panel. However, replacement fuses should not exceed 3 AMPS.
