5.5 HIGH TEMPERATURE ZONE AMBIENT THERMOSTAT CONNECTION (TA3)
Use an ambient thermostat (supplied as an accessory).
The contact of the ambient thermostat of the HIGH temperature zone (TA3) must be connected to the connector X7,
terminals 1 -2 of the MS UNIVERSALE+ (Figure 4).
Use a harmonised two-core cable "HAR H05 VV-F" 2x0,75 mm
5.6 CONNECTING THE BOILER ACTIVATION CABLE
Terminals 1 -2 of the connector X11 of the MS UNIVERSALE+ (Figure 4) must be connected to the input for the boiler
ambient thermostat (Terminal board M1).
Use a harmonised two-core cable "HAR H05 VV-F" 2x0,75 mm
5.7 CONNECTING THE EXTERNAL TEMPERATURE PROBE
(Available as an accessory)
The external probe connected to this appliance allows the delivery temperature of the mixed zone (first and second LOW
temperature zone) to be adapted to the variation of the outside temperature following the set curve.
The external probe must be connected to the connector X14, terminals 3-4 of the MS UNIVERSALE+ (Figure 4). Use a
harmonised two-core cable "HAR H05 VV-F" 2x0,75 mm
Te : outside temperature
TMIX : low temperature circuit delivery temperature
To adapt the delivery temperature of the non mixed zone (high temperature) to the variation of the outside tempe-
rature it is also necessary to install the boiler external probe.
In the presence of the remote control the delivery temperature of the first mixed zone will be lower than that set with the
control itself and with the potentiometers P1 and P2 of the MS UNIVERSALE+ board.
