NON-SERIOUS ALARMS
Thermostat OFF
■ Code A03 = water sensor error
■ Code A04 = remote humidity probe error (only if a remote
temperature probe is installed)
■ Code A05 = internal humidity probe error
N.B.: 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
FUNCTIONS IMPLEMENTED
■ 0x03 : Read Holding Registers
■ 0x04 : Read Input Registers
■ 0x10 : Write Multiple registers
EXCEPTIONS IMPLEMENTED
