The module also offers the following functions:
a. Remote valve: in addition to the relay on board the thermostat, an external relay on one of the modules on the Din bar of the home automation
bus can be used to control a remote electrovalve. To enable this function, check the "Remote valve control" box (for summer or winter) in the
confi guration program and enter the number of the module on which the relay is located. In this case, the relay must be number 1 on that
module. This relay follows the operation of the relay on board the thermostat.
b. Multi-speed: if multi-speeds are used (e.g. with a fan coil unit), the boxes "Speed" 1,2,3 must be checked (partial selection is also possible, e.g. 1
or 1 and 2). The corresponding relays are numbers 2, 3 and 4 on the same number module as used to control the remote valve (for summer and/
or winter). During confi guration, it is possible to enter the moment, in tenths of a degree, at which the next or previous speed level cuts in (e.g if
Speed 1-2 = 20 (default), the selected setpoint is 20° and the temperature detected is 19°; speed level 1 is enabled. If the temperature detected
was 17°, speed level 2 would be enabled. If Speed 1-3 = 50 (default) and the temperature detected was 14°, speed level 3 would be enabled).
c. Analysis interval: it is possible to indicate the time interval between one temperature setpoint check and the next. After checking, the thermostat
sends the temperature reading over the network, in addition to any activation or deactivation commands for the electrovalves and speed levels.
This is set by default to 60 seconds. A shorter interval could, if several thermostats are present, disturb data communication.
d. Delta: defi nes the interval in tenths of a degree between an activation/deactivation command and a deactivation/activation command (e.g. if the
setpoint is 20° and the delta 5 tenths of a degree, in winter the boiler will switch off at 20° and switch back on at 19.5°). This is set by default to
4 tenths of a degree.
e. Correction: if the temperature reading taken in the room by another instrument is slightly different to that displayed by the thermostat due to the
installation position of the latter, a correction coeffi cient, measured in tenths of a degree (this can also be negative), can be applied and added
to the actual temperature reading. This is set by default to 0.
f. Winter/Summer selector: if using a climate control unit with an input for changing its operation between heating and cooling modes, this input
can be controlled by the output indicated in the confi guration program. The output switches when the user, via the selector on the front panel
or the supervisor, sets the thermostat to winter or summer mode.
