Plugwise connection table

Connect Anna and Adam correctly to your boiler, heat pump and district heating.

Brands

Is your heat source not listed here? Please contact us and we will find out how it can be connected.

These connection details have been compiled with care. Our goal is that all information is correct and complete. But of course there can always be an error somewhere. We are not liable for any consequences of that error.

Control

OpenTherm

OpenTherm control is suitable for central heating boilers and heat pumps with an OpenTherm thermostat connection. The wires are polarity independent, so it doesn’t matter which wire you connect on the left or right.

With OpenTherm your heat source is controlled in a modulating way. This means that if little heating is required, a lower supply temperature can be requested. This makes it the most economical way of heating.

On/Off

On/Off control is suitable for central heating boilers, heat pumps and district heating with a 24V potential-free thermostat connection. The wires are polarity independent, so it doesn’t matter which wire you connect on the left or right. You can switch your heat source on or off via on/off.

You can often set the boiler temperature that is used on your heat source. You can set this lower to heat more efficiently. With the Adam HA you have to enter this temperature in the settings of Adam HA. This way Adam HA knows with which temperature to calculate.

 

Readjustment / Post regulation

For example with district heating, heat pumps and cascade control.

In some situations with district heating and heat pumps, hot water always flows around as soon as you open the radiator. With boilers and heat pumps, this is sometimes also referred to as weather-dependent control. There is therefore no thermostat present. Then use Adam HA with a zone control that controls the radiators and underfloor heating. Then you do not connect Adam HA to the heat source. Then, in Adam HA, turn on the Uncontrolled heat source feature in the advanced heating settings. Also enter the boiler temperature that Adam HA can use to calculate with. Then Adam HA opens the radiators and underfloor heating if that zone needs to be heated.

If Adam HA is used as a readjustment / post regulation, there must always be warm water flowing around. This situation is therefore not mentioned separately below.

Anna is not suitable for use as readjustment / post regulation. Then use Anna in combination with Adam HA and a zone control.

(1) Note: 230V on/off contact on the Daikin indoor unit. Use the Anna 230V for this. With Adam HA, use the Relay box 5V if you only want to heat. If you want to heat and cool, you need the Relay Box Heating and Cooling Heat Pump and the Cooling feature.
(2) Various settings have to be adjusted in the user interface so that the installation knows that it is controlled externally such as eg; Unit control method. For this, see the installation manual of the Daikin indoor unit.
(3) Make use of the Relay Box Heating and Cooling Heat Pump together with the Adam HA and the Cooling feature . You can’t cool with Anna.
(4) Heating and cooling control can also be controlled by a cooling contact. You then need the Relay box 5V and Relay box 230V . However, the recommended way is through the Relay Box Heating and Cooling Heat Pump.
