Heating and Cooling modes

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

Go to Settings → Virtual devices → Add virtual device → Multi-Value Switch section: Heating & Cooling.

Define which modes are supported

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


Winter	Summer	Spring, Autumn	Spring / Autumn

If you want to set different modes for every zone (or section of the house), you can define multiple Mode virtual switches. Go to Settings → Virtual devices → Add virtual device → Multi-Value Switch section: Heating & Cooling.

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:

Equitherm 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 (output actuator is controlling system that can produce both HOT and COLD)

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	Output actuator turns ON when desired temperature is higher than actual temperature	Output actuator is held in OFF state regardless of temperature
Cooling Mode	Output actuator is held in OFF state regardless of temperature	Output actuator is turned on when desired temperature is lower than actual temperature
Heating & Cooling Mode	Output actuator is turned on when desired temperature is higher than actual temperature	Output actuator is turned on when desired temperature is lower than actual temperature
Off (No heating, no cooling)	Output actuator is held in OFF state regardless of temperature	Output actuator is held in OFF state regardless of temperature

Example

Zone regulation of floor heating with hot water from boiler

Simple setup: Hot water is circulating in the pipes during heating season, and there is no circulation during cooling season (managed by boiler).

Set Mode to "Fixed heating"
Set Medium to "Hot (fixed)"

Automatic switching of Heating / Cooling modes

In order for the system to automatically switch the modes, add smart rule Equation for the multi-value switch Mode.
