Heating Circuit Parallel Shift - Rotex Controller Series Product Documentation

EbV
CAUTION To protect the floor heating systems against accidental overheating (malfunction –
manual mode) a controller-independent maximum temperature limit must be
provided. In this case a contact thermostat is recommended. By means of its
switching contact the control phase of the relevant heating circuit pump is looped.
The thermostat is to be set at the maximum permissible system temperature.
Operation:
8.2.1.5

Heating Circuit Parallel Shift

Function: For special applications this function offers the possibility to admit the heating
characteristic curve of the direct heating circuit with a constant shift value. The
demand value plus the shift value is transmitted to the heat generator.
The displacement of the heating characteristic curve is carried out in parallel with the
flow temperature.
Application: Base correction of the heating characteristic for adjustment to the desired room
temperature without changing the room setpoint.
Operation:
8.2.1.6 Heating circuit pump extended running time
Function: If there is no heat demand from the heating circuit, the heating circuit pump is
switched off after the time set in the relevant heating circuit menu to avoid a safety
switch-off of the heat generators at high temperatures.
