…an explanation for householders
TRVs sense the air temperature around
them and regulate the flow of water
through the radiator which they are
fitted to. They do not control the boiler.
They should be set at a level that gives you the room temperature you
want. These settings may have to be different in each room, and you
should set the TRVs to suit each room and then leave them to do their job.
Turning a TRV to a higher setting will not make the room heat up any
faster. How quickly the room heats up depends on the boiler size and
setting, and the radiator size. Turning the TRV to a lower setting will result
in the room being controlled at a lower temperature, and saves energy.
TRVs need a free flow of air to sense the temperature, so they must not
be covered by curtains or blocked by furniture.
TRVs cannot turn off the boiler when the house is warm. To do that, you
will need a room thermostat as well. The radiator in the room with the
room thermostat should not normally have a TRV, but, if it does, keep
the TRV on the maximum setting and adjust the room thermostat as
explained with the instructions.
Move the nut forwards and
tighten it firmly by hand
(do not use a tool).

3. Mounting

Rondostat can be mounted easily
on all common radiator valves
without causing any dirt or water
staining. You no longer require
the old thermostat head:
Loosen the mounted thermostatic
radiator valve.
Pull the thermostat head
from the valve.

How Rondostat works
Temperatures and control periods
Rondostat differentiates between two temperatures:
Comfort temperature (factory setting 21 °C)
Economy temperature
(factory setting 16 °C)
In automatic mode Rondostat changes between these
two temperatures in accordance with an adjustable
time program:
Heating period: Heating to comfort temperature
Economy period: Lowering to economy temperature
Time program
The heating and economy periods (the 2nd heating
period is optional) are specified by freely
programmable time programs. The factory default
setting for the time program is:
Heating period from 06:00 – 22:00
Economy period from 22:00 – 06:00

Rondostat is always awake!

Window function
If you open a window so that the temperature drops
quickly, the Rondostat closes the radiator valve in order
to save energy. The message is displayed.
When the temperature rises again or 30 minutes
have passed Rondostat opens the valve again.
You can also open the valve beforehand by pressing
the button or turning the adjustment dial.
Note: This functionality is only effective when the
Rondostat is located directly within the flow of cool
air from an open window.
Valve protection
If the valve has not been opened once completely
within the period of a week, Rondostat automatically
opens the valve briefly on Mondays in order to
prevent seizing (display ).
Frost protection
If the temperature drops below 4°C, the Rondostat
opens the radiator valve until the temperature rises
above 6°C again. In this way Rondostat prevents the
radiator from freezing.
PROG
Valve lift settings
Rondostat operates with a factory setting with the
