•
Use voltage-free remote control devices that are suitable to commutate very low loads (12V, 10mA).
•
Few inputs must be activated by configuration parameters whose access is reserved to authorized
assistance centers (in order to avoid unauthorized modifications)
ON / OFF FROM REMOTE CONTROL
Generally the unit is delivered with bridged terminals; if the control is not used, the bridge should not be removed.
SIGNALIZATION OF MALFUNCTIONING/ UNIT FUNCTIONING
Remote signalization of the proper function (ex. green light) or signalization of blocks of the machine (ex. red light).
Maximum voltage at the terminal ends is 24v ac and maximum power is 5a (ac1).
SECOND SET-POINT
It is possible to activate a secondary set-point with a remote contact (for example for the nighttime).
DEMAND LIMIT
It is possible to limit the absorbed electric power with an external signal of 10 Vcc or 4-20 mA.
Only an authorised service centre can perform the parameter configuration.
EXTERNAL AIR TEMPERATURE PROBE
Optional – It allows the automatic correction of the set-point according to the external air temperature.
For example, the summertime with low external temperatures, it is possible to have the internal comfort even with set-
points higher than the standard.
The parameter configuration must be carried out by an assistance center.
EXTERNAL AIR HUMIDITY PROBE
Optional – It allows the automatic correction of the set-point, according to external air enthalpy. The working process is
similar to the above mentioned process.
Only an authorised service centre can perform the parameter configuration.
WATER RESET
Optional – It allows the automatic correction of the set-point, according to an external signal of 4-20 mA or 0-10 vcc.
The working process is similar to the above mentioned process.
Only an authorised service centre can perform the parameter configuration.
