3 weekly switching programmes with up to 48 switching commands and one
calendar switching programme with up to 20 switching commands are
available. The minimum switching interval is 10 minutes or 1 day. Modes
from weekly and calendar switching programmes with lower energy
consumption take priority. The commands for the calendar switching
programme are retained.
The outdoor temperature is recorded by an EQJW 145 and is made available
to the remaining controllers as a measured value via the device bus.
Parameterisation for this purpose is performed in communication level.
Communication with the EQJW 145 is possible via the RS 485 interface with
the help of the Modbus RTU protocol. Data can be exchanged. The EQJW
145 is always used as a slave in this case.
A modem is used to send alarm texts to a mobile telephone as SMS, via a
provider. An interface similar to an RS 232 is used for this purpose. The TAP
(Telocator Alphanumeric Protocol) is used.
