Application of valves and thermostatic heads for radiators

The application of thermostatic heads on ICMA thermostatic valves is the best independent, simple and low-cost solution to automatically adjust the temperature, only where and when needed.

ICMA thermostatic heads allow the temperature in the environment in which they are installed to be constant.
The numbers on the handle represent the set temperature.

Temperature regulated in °C

Position of the thermostatic head

ICMA thermostatic heads do not require electricity; they are equipped with a liquid sensor with low thermal inertia and a coupling system to the valve body M28x1.5 (art. 1100) and M30x1.5 (art. 1101).

Selection of a thermostatic head and combination with a valve

1. Detect the connection to the valve body. In the case of ICMA products you will find the connection specified in the description of each valve.
2. Check the place of use. If the temperature detection is affected by the presence of curtains, choose items 987 or 990

Installation of thermostatic head

1.

Remove the protective cover from
the knob using a small screwdriver.

2.

Turn the knob in the counter clockwise direction to remove it completely from the valve.

3.

Unfasten the white adapter from
the valve body by simultaneously
pulling and bending it .

4.

Mount the grey ring supplied with
the thermostat control device on
the valve body. Keep the hexagonal socket turned toward the operator
(Only for valves with thermostatic option series 840)
