MYCOMFORT LARGE
SERIOUS ALARMS
Alarm code
-
Code 01 = error of external air temperature sensor (in case of on-board
thermostat)
-
Code 02 = error of internal air temperature sensor (in case of wall mounted
thermostat and disconnected external air temperature sensor)
NON-SERIOUS ALARMS
THERMOSTAT OFF
THERMOSTAT ON
-
Code 03 = water sensor error
-
Code 04 = external humidity probe error (only if a remote temperature sensor
is installed)
-
Code 05 = internal humidity probe error
NB: the alarm code is displayed only when the thermostat is switched off
MODBUS
The protocol implemented in the controller is Modbus RTU (9600, N, 8, 2) on RS485

Description of read-only registers [R]
-
"Status" Register
> On/Off: unit status (0: Off, 1=On)
> S/W: operation mode (0: S=cooling, 1:W=heating);
> P01: "on unit/wall-mounted" parameter
> Eco: Economy logic active
> Min.T: Minimum Temperature logic selected
> Alarm: general alarm indication (activated when any of the managed alarms is
triggered)
> Vc status of digital output Vc
> Vh: status of digital output Vh
> DI1: logical value of dig. input 1 (the physical status of the input depends on the
associated logic)
> DI2: logical value of dig. input 2 (the physical status of the input depends on the
associated logic)
> P07: "DIN 2 Logic" parameter
> P06: "DIN 1 Logic" parameter
> Dehum: dehumidification ON (0:no, 1:yes)
> P04: "water probe present" parameter
> DOUT1: Digital Input 1 status
> DOUT2: Digital Input 2 status
-
"Speed" Register: current operating speed of the indoor unit
