setting
The room temperatur alarm settings are
displayed if the room sensor is connected.
The amount of deviation between the measured supply water temperature and the controller de-
termined supply water temperature which causes an alarm when the deviation has lasted for the
time of the deviation alarm delay. To take the deviation alarm from use, set the setting outside of
the setting range. The deviation alarm is not allowed when; heating is on summer stop (see p. 12),
the controller is not on automatic or during the summer when the outdoor temperature is above
10°C and the supply water temperature is below 35°C.
A deviation alarm is given if the deviation is enough to cause an alarm (wee the previous set-
ting) and it lasts for the time period set here.
The controller gives a return water freezing risk alarm in addition to a lower and upper limit
alarm. The alarm limit for the freezing risk alarm is determined by the calculated return water
temperature (see p. 49).
A free lower limit temperature alarm that can be labelled.
A free upper limit temperature alarm that can be labelled.

You can set alarm limits from the controller’s alarm menu. Turn the control knob so the num-
ber is outside of the setting range to take the alarm out of use. The text “Not in use“ will
appear on the display. From the controller’s alarm menu you can check the controller’s ac-
tive alarms and what alarms have been active. If the controller has active alarms, the num-
ber of active alarms will appear in the main alarm menu.
