The maximum temperature measured by the floor temperature can be defined
within a range from 15 to 42°C. Damages to the floor in consequence of exces-
sive temperatures can thus be prevented (factory setting 42°C).
5. Entry of the connected load
(entry possible only when using the device as
room temperature controller with floor temperature controller function or as floor
temperature controller)
In order to allow to compensate the self heating of the HTRRUu, the power con-
sumption of the connected consumer needs to be entered. The power consumed
in consequence of the connected heating load is indicated in kW and can be
adjusted within a range from 0.1 to 2.3. With intermediate values, the nearest
lower value needs to be set. If actuating valves instead of controlling an electric
heating system, the low power consumption of these valves can be neglected,
so that no changes need to be made (factory setting 0.1).
6. Control methods
(available only when using the device as room temperature
controller with floor temperature controller function or as floor temperature con-
troller)
PI-PWM method (proportional–integral), recommended for the control of warm-
water and floor heating systems.
Two-point method (hysteresis), recommended for the control of electric direct or
storage heating systems (factory setting: two-point method).
7. External sensor
(connection possible only when using the device as room
temperature controller with floor temperature controller function or as floor tem-
perature controller)
The HTRRUu210.021 allows to connect external temperature sensors (NTC) with
resistance values of 2, 12, 15 or 33 kΩ. The actually used temperature sensor
needs to be selected here (factory setting 2 kΩ).
8. Reset function
Actuating this function resets all settings made outside of the experts menu
(except for time and date) to the condition as delivered.
