MONITORING CONTROLS WITHOUT USER INTERFACE
As shown in figure, inserting a VMF-IO expansion card makes it possible to control the fan coil cassette through the VMF-E5 panel or
through a third-party BMS without having a VMF-E4 user interface. For the fan coil to function properly, however, it is necessary to
install an air probe on the machine.
LED SYSTEM
The LED system in the thermostat gives the user information on how the system is functioning:
•
Lights up at a frequency of 1 second: Thermostat functioning properly
•
Lights up at a frequency of 100 ms: one of the following anomalies is affecting the thermostat
Ambient probe anomaly
○
fan coil in anti-freeze mode
○
alarm - water not suitable for operation.
○
user interface disconnected
○
inverter control alarm
○
condensate discharge alarm
