Leader in pellet boilers
13.7 Connecting temperature sensors
The sensor cables can be extended with min. 0.5 mm2 cables. Total cable length
for each sensor must not exceed 15 m. Boiler temperature sensor must be instal-
led in a thermometer well in the boiler jacket. Domestic hot water storage tank
temperature sensor must be installed in a thermometer well welded into the
storage tank. Mixing valve temperature sensor should be installed in a sleeve in
a stream of flowing water, however it can also be attached to the pipe, provided
the thermal insulation covers both the sensor and the pipe.
ALL SENSORS MUST BE SECURELY ATTACHED
TO THE MOUNTING SURFACE.
Ensure thermal contact between the sensors and the measured surface. Use
thermally conductive paste. Do not immerse sensors in oil or water. Sensor
cables must be led separately from mains cables. Otherwise, it may affect tem-
perature measurements. Minimum distance between cables is 10 cm. Do not
allow sensor cables to contact hot surfaces of the boiler and the heating system.
Temperature sensor cables are resistant to temperature up to 100°C.
13.8 Connecting weather compensator
The controller is compatible only with CT6-P weather compensator.
Install the weather compensator on the coldest wall of the building, usually
northern side, under roof. Do not expose to direct sunlight or rain. Install
the sensor at least 2 meters above the ground, at least 1.5 m from windows,
chimneys and other heat sources which may affect temperature measurements.
Use min. 0.5 mm2 cables with length up to 25 m. Cable polarity is not relevant.
Connect the other cable end to the controller terminals. Mount the sensor on the
wall with mounting screws. Mounting screw holes can be accessed by removing
the enclosure cover.
