3.2 Installation and connection

The following must be done before you install and connect the thermostat:

• AdjusttheboilersothatitcanbeconnectedtoanOpenThermthermostat.

• Turnofftheboiler.

Consult the boiler documentation for this process.

Do this as follows:

1. Open the housing by pulling the front and the base plate apart.

2. Attach the base plate of the thermostat to the wall using the

screws and plugs supplied. Ensure that the boiler’s connecting

wires are protruding through the hole in the base plate.

3. Connect the thermostat to the boiler OpenTherm connection

and the thermostat OT connection. OpenTherm is polarity

insensitive; you may therefore swap the wires.
