8. Cooperation with the room thermostat

9. Handling the controller

The controller has an input to connect the room thermostat of any kind, equipped with an nonvoltage
relay output. To the controller you connect the terminals of the thermostat which short-circuit if the
room temperature is higher than the preset one. Until the room temperature is lower than the preset
value in the thermostat (terminals of the relay opened) the controller operates normally. If the room
temperature exceeds the preset temperature in the thermostat (terminals of the relay short-circuited),
which is signalled by the icon on the display, the controller modifies its operation: the preset
temperature of the boiler is lowered to

If the thrmostat isn

t mounted then the corresponding input of the controller should be left

unconnected.

The thermostat ought to be located in the largest room of the building. In this room heater

thermostatic valves must not be mounted. The thermostat is to be placed at the height of approx. 1,5m
over ground, far away from windows and heaters. In the other rooms heater thermostatic valves may
be mounted.

45 C (

<29>

) and the CH pump runs

cyclically.

There are elements on the control panel (fig. 8).
The operation state is presented on the graphic display (2). The screens inform about the operation of
devices, temperature of sensors; they make it possible to change the parameters etc..The change of
screen is done by pressing the CHOOSE button (7). If this is the screen that is able to change a
parameter, press the CONFIRM button (6), which causes blinking of the parameter field to be
changed. By pressing

+

(4) or

-

(5) one can alter its value.

By clicking the CONFIRM button (6) one confirms the changes - the parameter field stops blinking.

The changed parameter not confirmed for 10 secs is not accepted by the controller and it recalls a
previous value of the parameter. The functions of the F1 (3) and F2 (8) buttons are variable. They
depend on the icons displayed in their vicinity.
