6.2.3.3 Single Stage Heater
The mode is determined by the outdoor temperature and the heating lockout
temperature settings.
This type of heating cycles one stage of heating to maintain the heating setpoint. You must
set a hysteresis value whereby the stage will turn on at the se hysteresis and turn at
setpoint.
The “Use Cool Outs” setting should be set to no for heater mode, where the output used for this
control will be the heating output NO1 on the expansion module.
Decreasing temperature turns
mode ON at se hysteresis
Increasing temperature
turns mode OFF at setpoint
