6.3.3 Switchover via binary input in room panel

The terminals 1 and 4 of the Type 5257-7 Room Panel can be bridged by means of an ex-
ternal floating contact (e.g. by a time switch with downstream contactor relay with floating
make or break contact). This enables the controller to switch to the rated operation mode
when the mode selector switch is set to reduced operation

or OFF/Frost protection

.

The following applies:

4

BI break contact

Operating mode is the same as the mode set at the mode selector
switch

4

BI make contact

Operating mode is rated operation,
regardless of the mode set at the mode selector switch

Frost protection

If the controller is in the operating mode OFF/Frost protection (see section 6.3), frost protec-
tion measures are initiated if the following applies:

4

Outdoor temperature < 3 °C (outdoor temperature compensated control)
The flow set point is set to 20 °C. The binary output remains activated until the outdoor
temperature rises above 3.5 °C.

4

Flow temperature < 15 °C (control with reference variable (room temperature))
The flow set point is set to 20 °C. The binary output remains activated for 5 minutes. After
that, the heating is deactivated when the flow temperature is higher than 15° C.

6.5

Return flow temperature limitation

The temperature difference between the flow and return flow in a network indicates how well
the energy is used: the greater the difference, the higher the efficiency.

A return flow sensor is sufficient to evaluate the temperature difference when the network
flow temperatures are predetermined. The flow temperature set point is reduced when the
Max: return flow temperature measured at the return flow sensor exceeds the Flow tempera-
ture set point:
The reduction amount is calculated from the deviation of the return flow temperature multi-
plied by the factor

Kp Return flow temperature limitation. The rate at which the return flow

temperature is reduced by the calculated amount is determined by

Tn Return flow tempera-

ture limitation.
