switching programme is not enabled. The commands in the yearly switching
programme are not deleted after they have been executed.
The outdoor temperature is registered by an EQJW 125 and is made
available to the remaining controllers as a measured value via the device
bus. The parameterisation for this purpose is performed in the communication
level.
EN 1264, Part 4 describes how anhydrite cement floors should be treated
during operational heating before the floor covering is laid. This entails, first of
all, maintaining an inlet temperature of 25°C for 3 days. Thereafter, the
maximum inlet temperature should be maintained for four days. This function
has been included on the EQJW 125; it can be activated via the SERVice
level.
In addition, the controller has a screed curing facility. This involves gradually
increasing the flow temperature, starting at 25°C, by 5 K per day until the
maximum flow temperature is reached, which is maintained for 7 days.
Thereafter, the flow temperature is reduced gradually by 5 K per day until it
has again reached 25°C. These functions are called up from within the
SERVice level.
Communication with the EQJW 125 is possible via an RS 485 interface with
the help of the Modbus RTU protocol . Data can be exchanged. The EQJW
125 is always used as a slave in this case.
An additional modem is used to send alarm texts as SMS to a mobile
telephone, via a provider. An interface similar to an RS 232 is used for this
purpose. The TAP protocol (Telocator Alphanumeric Protocol) is used here.
The settings are made in the communication level.
