Function test

As-the end of the assembly of the thermal expansion valve a
function test must be carried out.
For this you must proceed as follows:
1 Turn the knob of head till position 0.
2 Turn on the heating system and check that radiator is not heated.
3 Turn the knob of the head till position "5" and check that
radiator will heat up.
Remark: The test has to be performed with environment tem-
perature < than 26 °C.

Instructions for use

5 Functioning
The head with thermal sensor constantly controls room tem-
perature. It compares the measurement with the value you set
and acts on the valve for its opening or closing. If room tem-
perature is lower than that set by you, the valve opens until the
desired temperature is reached.
If the thermal exchange conditions are inadequate for the en-
vironmental needs (due to a reduced exchange surface, a low
carrying liquid temperature or an insufficient differential pres-
sure valve) the desired temperature may not be reached. In this
case, it cannot be attributed to a product defect.
When room temperature goes beyond the set value, the valve
closes.
