Introduction

Winter/Summer season functionality

Main purpose of Winter/Summer season functionality is to control night cooling and relative humidity in winter or summer season.

Season changeover can be done:

  • manually
  • by date
  • automatically with temperature sensor (PT1000)

Night Cooling for Summer season:

If controlled System type is Ventilation & Heating (HVAC menu) with duct heat exchanger for air temperature control in Summer device will not activate heating if supply air temperature is below set point.

Relative humidity control depending on season:

If C35HV device has relative humidity sensor it will activate air flow when relative humidity is higher then set point. Depending on geographic location this option can be useful only in Summer or Winter so it can be enabled or disabled for specific season in HVAC menu
