Glossary
Switch-on room temperature:
The usage of the room sensor in the remote control
devices (RCD) or operating unit (in this case the opera-
ting unit should be inserted in the VR 55 mounting box
(accessory)) can be parameterised for each heating cir-
cuit. Factory (setting)
The switch-on room temperature is used to include the
current room temperature in a reference room in the
calculation of the flow temperature. The room tempera-
ture sensor of the assigned RCD is used if the function
is active. The value of the operating unit is used if no
RCD is available. (As a result it is possible to use the
operating unit also in a reference room for this function
by means of a wall mount.)
Target flow temperature
Represents the inlet temperature in a heating circuit
calculated by the controller on the basis of the pre-set
parameters.
Temperature correction for actual room temperature
You can shift the displayed value for the room tempera-
ture up or down within a range of +/–3 °C as required.
Temperature fault detection
With this function it is possible to detect faults regar-
ding the setting or layout in a heating circuit. If the sti-
pulated target temperature is still not reached after a
longer time period (parameterisation: OFF, between 1
and 12 hours), an error message appears for the circuit
in question.
Default setting: Off
Test mode
In test mode you can test and actuate every single sen-
sor, each pump and each mixer per heating circuit sepa-
rately.
3. Difference Control
Operation:
if TD2 > TD1 + switch-on difference (Menu C5), then
output MA is activated
if TD2 < TD1 + switch-on difference (Menu C5), then
output MA is switched off again
In the hydraulic plans 1-4, the 3rd differential control
serves as heating support.
In all other plans the 3rd differential control is not
available.
