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 configuration 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 configuration, 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: defines 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 coefficient, 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 configuration 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.
