When the thermostat is in the AUTO mode, it will operate according
to the times that have been programmed. The user can select from 6
dierent programs per day - each with a time and a status of ON or OFF.
When program is scheduled to be ON, it will remain on until the next
OFF program.
During this time the thermostat will remain ON until the temperature
setpoint is reached.
There is only one temperature setpoint which is applied to all programs.
The default temperature setpoint is 60˚C.
60˚C is the temperature level required in order to prevent the build up
of legionella bacteria.
How your cylinder thermostat works
9
RFRP-HW-OT Room Thermostat CP4-HW-OT
ON CYLINDER: To ensure accurate control of your cylinder, the
temperature sensor should be mounted on the bottom 1/3 of the
cylinder. It is essential that the sensing element is in direct contact with
the cylinder and that there is no insulation between it and the cylinder.
The temperature sensor can be xed to the cyliner using the provided
foil tape.
ON PIPEWORK: To ensure accurate control, the temperature sensor
should be mounted on the pipework as tightly as possible. It is essential
that the sensing element is in direct contact with the pipework and that
there is no insulation between it and the pipework. The temperature
sensor can be xed to the pipework using foil tape.
IN THERMAL POCKET: To ensure accurate control, the temperature
sensor should be inserted into the thermal pocket. It is essential that
the sensing element is inserted as far as possible. The temperature
sensor can be xed using the provided foil tape.

1) The mounting height should be 1.5 metres above the oor level.
2) The place of installation should be chosen so that the sensor can
measure the temperature as accurately as possible.
Choose the mounting location to prevent direct exposure to
sunlight or other heating / cooling sources when mounted.
3) Fix the mounting plate directly to the wall with the screws provided.
4) Attach the thermostat to the mounting plate.
5) Lower the ap at the front of the thermostat. There is a battery
