Heating and Cooling modes

Smart rules for regulation of temperature have unified setting for switching between heating and cooling modes.

Define which modes are supported in your location

In order to manage activation of heating or cooling within location, use predefined virtual multi-value switch Mode.

Winter	Summer	Spring, Autumn	Spring / Autumn

1. To adjust Mode switch to show only modes that are relevant for specific location, use Service Settings of Mode multi-value switch.
   
2. In Service Settings, open DEVICE tab and turn on/off specific modes.

Set behaviour of heating / cooling smart rules based on Mode value

Mode is supported in smart rules:

• Temperature hysteresis controller
• Temperature PID controller

Partial support for Mode is also in:

• Equithermic regulation
• Blinds adjustment according to sun

Type of Medium that is controlled by output actuator

Medium is e.g. water running in pipes, and you can select between 2 types plus dynamic switching based on reed contact or switch device:

• HOT (increasing temperature when output actuator is open) or
• COLD (decreasing temperature if output actuator is open)
• DYNAMIC

Table below shows behaviour of hysteresis and PID smart rules based on type of Medium and value of Mode switch:

	Medium: HOT	Medium: COLD
Heating Mode	Hysteresis controller enabled  PID controller enabled Output actuator is turned on when desired temperature is higher than actual temperature	Hysteresis controller disabled  PID controller disabled Output actuator is held in OFF state regardless of temperature
Cooling Mode	Hysteresis controller disabled  PID controller disabled Output actuator is held in OFF state regardless of temperature	Hysteresis controller enabled  PID controller enabled Output actuator is turned on when desired temperature is lower than actual temperature
Heating & Cooling Mode	Hysteresis controller enabled  PID controller enabled Output actuator is turned on when desired temperature is higher than actual temperature	Hysteresis controller enabled  PID controller enabled Output actuator is turned on when desired temperature is lower than actual temperature
Off (No heating, no cooling)	Hysteresis controller disabled  PID controller disabled Output actuator is held in OFF state regardless of temperature	Hysteresis controller disabled  PID controller disabled Output actuator is held in OFF state regardless of temperature
