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


  1. To adjust Mode switch to show only modes that are relevant, use Service Settings of Mode multi-value switch.

  1. 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

(tick) 

Output actuator turns (/) ON when desired temperature is higher than actual temperature

(error) 

Output actuator is held in (X)OFF state regardless of temperature

Cooling Mode

(error)

Output actuator is held in (X) 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)

(error) 

Output actuator is held in (X)OFF state regardless of temperature

(error) 

Output actuator is held in (X)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.

Example:

Dynamic type medium workaround

If you use a machine (e.g. heat pump) that is able to produce both heating and cooling medium via the same output actuator, Dynamic type of medium is required for proper configuration.

There are two possible scenario:

1.Heat pump is in automatic mode and switches between hot and cold automaticaly by itself. TapHome just reads the reed contact with the actual type of medium.

  • Create reed contact input and use Device type "Heating & Cooling"



  • Go to Thermostat and add "Temperature hysteresis controller"Smart Rule. In the Smart Rule use Heating & Cooling mode fixed and as Medium select reed contact prepared in previous step.



2.Heat pump is in manual mode and the TapHome switches between hot and cold using output relays that control auxillary inputs on heat pump.

  • Create virtual switch "Medium" and use "Heating & Cooling" device type within the service settings


  • Create the configuration where TapHome relays managing the type of medium on Heat Pump switch virtual switch "Medium" automatically from Cooling to Heating and viceversa. This will keep the Medium switch everytime in the right state (Heating or Cooling) in line with the heat pump.
  • Go to Thermostat and add "Temperature hysteresis controller"Smart Rule. In the Smart Rule use Heating & Cooling mode fixed and as Medium select switch Medium prepared in previous step
