HTR24(20) is a surface-mounted (or on a flush-box) room thermostat
dedicated for surface heating / cooling control, characterized by high thermal
inertia. It is connected to the wiring centre, through which you can lower the
set temperature on it, receiving a signal NSB (night temperature reduction)
from the weekly thermostat. The room temperature could be set by knob
use. Thanks to the built-in algorithms, it offers much better temperature
control accuracy than traditional mechanical thermostats. The thermostat is
characterized by silent operation.

Note!
The ideal position to thermostat mounting is about 1,5m under floor level
far from heating or cooling sources. In addition, the thermostat should not be
installed behind curtains or other obstacles or in places with high humidity, as
this will prevent accurate measurements of room temperature. The thermostat
must not be exposed to sunlight. Do not place the thermostat on an outer wall.
The product complies with the following EU directives: 2014/30/EU,
