The QAD36/101 strap-on sensor is used when a plate heat exchanger is installed between the
primary and secondary circuits or a 3-way mixing valve is being used on the system. The hydraulic
header sensor, DHW sensor or the solar sensor are plug in (bulb type) sensors so they need a sink
to be plugged on the so called sanitary member.
Room Thermostat
Whether it is singular or a cascade system, it is able to make 3 room thermostat connection inputs.
There can be placed a room thermostat per different three zones (places to be sensed and controlled).
In other means, LMS 14 can be connected to different three room thermostats at the same time.

In this case, the three
different zones will
be able to send their
heat demands as
digital signals (ON /
OFF) to the mainboard
(LMS 14). The room
thermostat connections
should be made via the
room thermostat input
terminals H4, H5 and
H6 of LMS 14.
