systems with water heater needs preliminary heat up
Heat up – in systems with water heater if the anti-frost thermostat
sends an alarm, the water heater heat up is initiated
Cool down – in systems with electrical heater and DX cooler or HPM/
CM module the fans are stopped after cool down time once the elec-
