12.1.31 RTC - Basic load
Name
Object function
Data type
RTC: Basic load
Input
1.001 Switching
A parameterized basic load can be activated via the 1-bit communication object. I.e. a minimum
control value that is larger than zero is activated by sending value "1".
The basic load is deactivated by sending value "0". When the setpoint temperature is reached
the control value can be reduced up to zero without taking the parameterized minimum value
into account.
Notice
Deactivating the base load for a floor heating system is always useful in the
summer, since it saves heating energy.

1. Output
1.001 Switching
2. Input
3. Input/output
1. Automatic:
– When the switchover between heating and cooling is carried out automatically by the
RTC, the current status is sent o the bus via the communication object. Here the status
"Heating" has value "1" and status "cooling" has value "0".
2. Only via object:
– The switchover between heating and cooling is carried out in the RTC only via the
communication object. Here the heating mode is activated with the receipt of value "1"
and the cooling mode with value "0".
3. On-site/via extension unit and via object:
– Switching between heating and cooling on the room temperature controller occurs in the
RTC by user interaction or via the communication object. The current status is sent to
the bus or received via via the object. Here the status "Heating" has value "1" and status
"cooling" has value "0".
