4.7.8  2-stage heating or cooling

On 2-stage applications, the thermostat controls 2 valves or compressors in heating or
cooling mode or changeover (automatic or manual).
"Cooling only" is factory-set (P01=1).

In heating mode, the 1st stage is activated if the acquired temperature is below the
setpoint.
The 2nd stage is activated if the acquired room temperature drops below "setpoint"
minus "setpoint differential".

In cooling mode, the 1st stage is activated if the acquired temperature is above the
setpoint.
The 2nd stage is activated if the acquired room temperature rises above "setpoint"
plus "setpoint differential".

The diagrams below show the control sequence for 2-position control.
