Heating and Cooling modes

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

doc_tap_Smartmodes;

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

doc_tap_SettingsCooling;

Define which modes are supported

doc_tap_Dms;

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


Winter	Summer	Spring, Autumn	Spring / Autumn
doc_tap_Winter;	doc_tap_Summer;	doc_tap_SpringAut;	doc_tap_SprAutumn;

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

doc_tap_behaviour;

Mode is supported in smart rules:

Temperature hysteresis controller
Temperature PID controller doc_tap_Modecontroller;

Partial support for Mode is also in:

Equitherm regulation
Blinds adjustment according to sun
doc_tap_Modesun;

Type of Medium that is controlled by output actuator

doc_tap_Mediumactuator;

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)
doc_tap_MediumCOLD;

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

doc_tap_Tableswitch;

	Medium: HOT	Medium: COLD
	doc_tap_MHOT;	doc_tap_MCOLD;
Heating Mode	Output actuator turns ON when desired temperature is higher than actual temperature	Output actuator is held in OFF state regardless of temperature
doc_tap_HeaM;	doc_tap_ONhigher;	doc_tap_OFFstatet;
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
doc_tap_CoolMo;	doc_tap_OFFstatetemper;	doc_tap_ Outputactuatorlow;
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
doc_tap_HCMod;	doc_tap_ Outputahigher;	doc_tap_ Outputaclower;
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
doc_tap_Noheat;	doc_tap_oaoffs;	doc_tap_oaoffstate;

Example

doc_tap_Ex;

Zone regulation of floor heating with hot water from boiler

doc_tap_ Zoneboiler;

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)"
doc_tap_ Simplefixed;

Automatic switching of Heating / Cooling modes

doc_tap_ AutomaticHC;

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

Example:

doc_tap_EquationMode;

Dynamic type medium workaround

doc_tap_Dynamicw;

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:

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"
doc_tap_IfCooling;

Go to Thermostat and add "Temperature hysteresis controller" smar rule. In the smart rule use Heating & Cooling mode fixed and as Medium select reed contact prepared in previous step
doc_tap_Thermostatstep;

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.
doc_tap_Heatpump_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" smar rule. In the smart rule use Heating & Cooling mode fixed and as Medium select switch Medium prepared in previous step.
