17.7. Room temperature controllers
There are different selectable controller types with different functionalities. In the following, their different properties will
be described. In most cases, a simple 1-stage heating should be sufficient.
17.7.1.
Heating vs. Cooling controller
Heating
IIf a heating controller is used or the controller is in heating state (heating/cooling controller), and the actual temperature
falls below the current setpoint (corresponding to the actual mode, e.g. stand-by), the controller, if enabled, starts
heating, according to the used controller type (e.g. PI-Controllers, selectable in the parameters).
Cooling
Cooling mode works vice versa to the heating mode, so if the temperature rises over the current setpoint, the controller
starts cooling.
17.7.2. One-
vs.
Two-stage controllers
One Stage
One-Stage controllers have only one controller that allows to control the current setpoint.
Two-stage
Two-stage controllers have two controllers, each separately configurable. The first stage controller controls on the
current setpoint (depending on mode, setpoint adjustment and heating/cooling gap), the second stage controls the actual
setpoint plus/minus the parameter "1st/2nd stage bandgap (Temp. Controller Heating/Cooling), Page 121".
Comparison: see figure. 2-stage cooling controller in comfort mode, with comfort setpoint at 20 °C, no setpoint
adjustment, no heating/cooling gap and parameter "1st/2nd Stage Bandgap" is 2 °C. If the temperature exceeds 20
°C, the first stage starts to
work and tries to reduce the temperature to 20 °C. If the temperature still rises and then exceeds 22 °C (20 °C + 2 °C),
the second stage starts working and tries to keep the temperature below 22 °C.
