The changeover from Heating to Cooling or Vice Versa is dependant on a number of parameters and settings.

Should the Fresh Air Temperature be less than 18 (adjustable threshold on screen Ac25), then the controller will force the control mode in HEATING


Should the Fresh Air Temperature be more than 28 (adjustable threshold on screen Ac25), then the controller will force the control mode in COOLING


Should the Fresh Air Temperature be between 18 and 28 (adjustable threshold on screen Ac25), then the changeover is Automatically carried out based on the supply temperature values as follows:


If the Supply Temp > 26 C Deg (Cooling set) on screen Aa04, THEN the Controller will operate in Cooling mode. The controller will remain in cooling mode unless the supply temperature drops below 20 C Deg (Heating set) on screen Aa04


If the Supply Temp < 20 C Deg (Heating set) on screen Aa04, THEN the Controller will operate in Heating mode. The controller will remain in Heating mode unless the supply temperature rises above 26 C Deg (Cooling set) on screen Aa04
