MYCOMFORT LARGE
- H15 = OFF
- H16 = ON
- H17 = OFF
- H18-H23 = 25°C
- H24-H29 = 22°C
- H30-H34 = 1
- H35-H36 = 2
- H37 = 24H
If the 12H display mode has been set (parameter H37), for configuration parameters
H01 to H11 (except H03) the display will not show the sequential number of the
parameter but rather the hourly situation expressed in AM/PM.
DISPLAY
If the time programming function is enabled, when the thermostat is on the clock symbol
will always appear and it will be possible to check whether the time settings are correct
(only for a few instants) by simultaneously pressing the SEL+MODE buttons. When
the thermostat is off, the clock symbol and current hour will appear constantly on the
display only if the ON/OFF time programming mode is enabled.
ALARMS
This control governs two types of alarms:
- Serious Alarms cause the forced switching off of the thermostat
- Non-serious Alarms do not cause the forced switching off of the thermostat, but
disable possible critical functions
SERIOUS ALARMS
- 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
Alarm code
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
