DAIKIN P1P2 Aux Heater Wiring
Introduction
- Aux heat is supported in P1P2 (VRV, SkyAir) and S21 (single/multi-split) systems
- The aux heat source cannot require the indoor unit fan, just controlled from the thermostat.
- The thermostats Aux outputs are dry contacts that close the connection to turn on the aux equipment.
- A 24V AC control signal must be routed through the aux contacts.
Aux Heat Setup on Daikin One+
- An aux heat source can be added in the “Equipment Setup” menu using “add equipment”.
- The Aux heat can be setup as primary or the secondary source of heat. Once added, Emergency heat mode will also be added to the system mode menu.
- Setup Aux heat source
- Click on Add equipment / aux Heat source
- Select Connection: select aux1 or aux 2 based on Wiring connection to AUX heater
- Default: heat pump is primary heat source.
- Select control to adjust parameters
Set-up of Heat Pump as Primary Heat Source
Note: the heat pump lockout and the AUX heat lockout are based on the
ambient temperature data. The Ambient temperature data is communicating to the
ONE+ through the weather service, therefore the Wi-Fi connection is necessary
for AUX heat logic to execute.
Operation with Heat Pump as Primary Heat Source
- Heat pump is primary heat source
- Heat pump lockout adjustable from -20°F to 65°F in 5°F increments. (default 15°F)
- Aux heat lockout adjustable from -10°F to 75°F in 5°F increments. (default 50°F)
- Aux heat demand
- Ton differential -7°F to -3°F in 1°F increments (default -3°F)
- Toff differential -4°F to 1°F in 1°F increments (default 1°F)
Set-up of Aux Heat as Primary Heat Source
Operation with Aux Heat as Primary Heat Source
- Aux. is primary heat source
- Heat pump lockout adjustable from -20°F to 65°F in 5°F increments. (default 15°F)
- Setpoint differential -9°F, -7°F, -4°F, and -2°F (default -2°F)
- Aux heat demand
- Ton differential -1°F to -2°F (default -1°F)
- Toff differential 1°F fixed
Independent Aux Heater Operation
The aux heater operates independently from the master’s mode.
