THERAPRO HR90
Parameter 13 – Temperature
offset
Since the radiator controller measures the room
temperature in the area of the radiator, it is possible
that this temperature deviates from the temperature
measured at a different point in the room.
If, for example, 68 °F is measured in the room and
70 °F at the radiator, this effect can be compensated
by an offset of 30 °F.
Parameter 15 – Display of the
valve position
When this parameter is activated (setting "1"), the
calculated valve position (0 to 100% opened) is
displayed momentarily.
The main display is shown again after approx. 3
minutes or when the AUTO button is pressed.
Parameter 16 – Valve exercise
day
If the radiator valve has not been opened once
completely within the period of 2 weeks, a self-test
(forced operation) is carried out. The radiator
controller opens the radiator valve briefly on the
subsequent Monday (factory setting) in order to
prevent seizing.
The weekday for valve protection can be selected
freely
Parameter 17 – Window open
function
• If a window contact is connected, the parameter is
set automatically to "2" (cabled). The window
function is controlled by the window contact.
*This is not currently an option for the US market, so
parameter must be set to 0 or 1.

10. FURTHER FUNCTIONS

Monitoring functions
Window function
If you open a window causing the temperature to drop,
the radiator controller closes the radiator valve in
order to save energy.
WINDOW is displayed.
When the temperature rises again, but at the latest
after the set period (factory setting: 30 minutes), the
radiator controller opens the radiator valve again.
You can also open the radiator valve beforehand by
pressing the AUTO button or turning the adjustment
dial.
33-00084EFS—03
The sensitivity of the radiator controller to a
temperature drop or temperature rise can be set, see
Section 9, Parameters 5 to 7.
If a window contact is connected, the window function
reacts directly to the opening and closing of the
window, see Parameter 17.
Valve protection
If the radiator valve has not been opened once
completely within a period of 2 weeks, a self-test
(forced operation) is carried out. The radiator
controller opens the radiator valve briefly on the
subsequent Monday (factory setting) in order to
prevent seizing.
CYCL is displayed.
The day for the valve protection can be set in
Parameter 16.
Frost protection
If the temperature drops below 41 °F, the radiator
controller opens the radiator valve until the
temperature rises above 43 °F again. This prevents the
heating system from freezing up.
FROST is displayed.
NOTE: The heating must be switched on to ensure
the frost protection function.
Manual override
If you have switched off the central heating system in
summer and do not want to waste the batteries of the
radiator controller, you can close the radiator valve
continuously.
Closing the valve
1. Press the button AUTO/ECO/MANU until MAN-
UAL is displayed.
2. Turn the adjustment dial counter-clockwise until
OFF is displayed.
The radiator valve now remains closed. The valve
and frost protection functions continue to be
active.
Opening the valve
Use the AUTO/ECO/MANU button to change to
automatic mode.
– or –
Set the desired temperature in manual operation.
Child-proofing / Operation lock
You can block the radiator controller to protect it
against unauthorized operation:
• Keep the AUTO/ECO/MANU and PROG buttons
pressed simultaneously for at least 3 seconds.
The lock symbol is displayed.
NOTE: The same key combination is used to release
the radiator controller again for operation.
