Disabling radiating panel heads
Disabling radiating panel heads
NOTE:
– Radiating panel h cooling.
– All the safety limit microswitches are connected in parallel to the LOW TEMPERATURE CIRCUIT REQUEST input (NO dry contact)
– Fan convectors cooling/dehumidifying only
– The RH (humidistats) activate the fan convectors and the corresponding heads and disable all the other radiating panel heads.
– Furthermore, the UR provide the request to LOWER LOW TEMPERATURE CIRCUIT SETPOINT (NO dry contact).
– The request to the remaining head is always supplied by the TA (ambient thermostats).
