2 .6 Connecting the low temperature
thermostats
The
Connect LE
are equipped with a low temperature limit thermostats
(TB) that protect the zones of low-temperature above 55 °C.
b
Do not connect the low temperature limit thermostats (TB) in case of
high temperature system.
For installations on low temperature system (floor) to choose one of the
following links:
- boiler - connect the low temperature thermostat TB, brown wires (MA)
and blue (BL), the input of TBT boiler (see installation manual for con-
nection and operation of the boiler in case of intervention of at least one
of the thermostats TB).
- Connect - connect the low temperature thermostat TB inside the electri-
cal panel of the module, removing jumper purple (VI) and connecting the
wires brown (MA) and blue (BL) in place of the jumper previously remo-
ved.
In case of intervention of at least one of the thermostats TB will stop the
power to all the circulators and the request to the boiler until normal oper-
ating conditions are restored.
