The relay changes its mode according to its week/24 hour program. The controller’s display
shows the present control mode. The relay’s week/24 hour program can also be found under
clock programs. Set the time for relay control. Select the mode for the relay at the set time.
Then select the days of the week that relay control is to be used.
Example: The floor is heated using night time electricity.
Creating the week/24 hour program for the relay:
Press OK at the “Add new” row.
Press OK. Set the time for relay control (set the hours and minutes separately) and Press OK
to confirm the time.
Press OK, then turn the control knob to set the mode for the relay and press OK to confirm.
Press OK at each day of the week that the control command is to be set for. Press OK at the
end of the row to confirm the new time program. Press ESC to exit.
In the example, relay control is activated Sunday - Friday from ten p.m. to six a.m.

Key word:
Relay control
Send a message: Relay control . The controller sends a return message with a * in front of the
control mode in use (auto/ON/OFF). If you want to change the control mode, move the * in front
of the desired control mode and send a message back to the controller. The controller sends
a return message showing that the controller has changed the control mode.
Two temperatures are compared, e.g. solar collector temperature and accumulator tempera-
ture. When the temperature difference grows big enough (e.g. 10°C), the solar collector charge
pump starts. When the temperature difference gets small enough (e.g. 2 °C), the pump stops.
In hybrid heating, the relay is used to control the charge pump:
