THERAPRO HR90
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.
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.
33-00084EFS—02
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 MANUAL
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.
