4.1 - Electronic regulation for 2 circuits
The electronic regulation is designed to control 2 distinct circuits:
• a 1
st
direct heating circuit (without mixing valve)
- radiators or underfloor heating
- with or without exterior sensor
- with or without ambient temperature control
• a 2
nd
priority circuit for domestic hot water (DHW)
- with DHW sensor
or
- with DHW aquastat
4.1.1 - General functions of the electronic
regulation
• Operation with or without an ambient temperature thermostat
or sensor.
• Operation with or without using the heating circulator
controlled by the ambient temperature thermostat’s demands.
• Manual or automatic operation (with exterior sensor).
• With exterior sensor: with or without automatic summer/winter
changeover.
• Automatic correction of the heating curve or of the set
temperature with the presence of an ambient temperature
thermostat without timer or an ambient temperature sensor.
• Management of the domestic hot water using a DHW sensor or
DHW aquastat.
• Pairing of the power stages in three-phase operation.
• With DHW sensor: anti-legionellosis function for the domestic
hot water (every 24h the DHW is raised to 65°C for 10 minutes).
• Programming the maximum power of the boiler (selection of 1
to 6 power stages from 6 possible stages).
• Timeout between start-up and stopping of the 6 power
stages (adjustable from 1 to 6 minutes) with protection from
overheating).
• Weekly rotation of the 6 power stages.
• Counting of the number of cycles for the engaging of the 6
power stages.
• Post-operation of the heating circulator and of the DHW 3-way
valve.
• Unblocking of the heating circulator while in summer mode.
• Frost protection of the heating and domestic hot water circuits
when the boiler is stopped.
• Timer input from a lowering of the boiler’s set temperature in
eco mode (or frost protection mode) or for authorisation for the
production of DHW.
To avoid permanently blocking the circulator and
to allow for the automatic unblocking function
every 24 hours, it is IMPORTANT TO LEAVE THE BOILER
SWITCHED ON (circuit breaker engaged) during any
prolonged period of stopping (standby mode or summer
mode)
If the circulator becomes blocked after not having followed
these instructions, the warranty will be null and void.
