MAXIMUM HUMITIDY

If the current humidity level is higher than the maximum humidity, cooling will be disabled in a given zone.

NOTE

This function is active in the Cooling mode when the humidity protection function is switched on (Menu -> Zone -

> User settings -> Cooling -> Humidity protection) and a humidity sensor is registered in the zone.

L-8 may control an additional valve via a valve module (e.g. i-1m). The regulators connect using RS communication but the

registration process is necessary. There is a range of parameters enabling the user to adjust the valve operation to individual

needs.

Configuring additional valve parameters is possible after the valve has been properly registered by entering the module

number (found on the rear part of the module housing or in software version screen).

8.1.

This function enables the user to enable or disable the valve.

8.2.

This function is define the pre-set valve temperature. The temperature is read from the valve sensor.

8.3.

This function enables the user to calibrate the built-in valve at any time. During this process the valve is restored to its safe

position – in the case of CH valve it is fully opened whereas in the case of floor valve it is closed.

8.4.

This is the maximum single stroke (opening or closing) that the valve may make during one temperature sampling. The smaller

the single stroke, the more precisely the set temperature can be achieved. However, it takes longer for the set temperature

to be reached.

8.5.

The parameter determines the smallest valve opening. Thanks to this parameter, the valve may be opened minimally, to

maintain the smallest flow.

8.6.

This parameter defines the time needed for the valve actuator to open the valve from 0% to 100% position. This value should

be adjusted to the value given on the actuator rating plate.

8.7.

This parameter determines the frequency of water temperature measurement (control) downstream of the CH valve. If the

sensor indicates a change in temperature (deviation from the pre-set value), the electric valve will open or close by the pre-

set stroke, in order to return to the pre-set temperature.
