1. The domestic hot water circuit must be equipped with a pressure safety valve, set at a maximum of
8 bars.
2. The cold water supply connection must be
equipped with the following valves as a
minimum requirement, and fitted to the tank
in the indicated order:
²Stop cock.
²Non-return valve.
²Safety valve set at < 8 bars.
When the main water pressure exceeds 5.25
bars, a pressure reduction valve must be
installed upstream of the above-mentioned
valves.
"Domestic hot water safety modules" include
the required valves in a single unit.
Outflow from the safety valve must always be connected to a drainage system.
Outflow or leakage from the safety module must always be allowed to drain freely. The water discharge
pipe work must remain open to the atmosphere.
3. Once the tank is installed, first fill the domestic hot water system and pressurise it.
4. Once item 3 is completed, fill the PAC's primary circuit.
5. Place the dielectric sleeves on the secondary circuit connections to avoid contact with the copper
pipes.
6. Bleed the air from the circuits after filling with water.
7. It is normal to observe a volume of discharged water during heating (expansion). This volume of
water can reach 3% of the water accumulator's capacity.
8. The safety valve must be operated at least once a month (by triggering the system drainage
device).

DOMESTIC HOT WATER PRODUCTION REGULATION
The PAC controller manages domestic hot water production in accordance with the following operating modes:
²COMFORT MODE
Domestic hot water production has priority over heating except when the ambiance temperature /
set temperature difference is greater than 2° C (Maximum one hour).
²ECONOMY MODE
Domestic hot water is produced during off-peak hours (dry contact) or in accordance
with times programmed in the controller.
Option: Possibility to restart domestic hot water production outside off-peak hours if the water
temperature has reached a programmable minimum temperature.
²IMMEDIATE DOMESTIC HOT WATER PRODUCTION
The PAC's regulator enables domestic hot water production to be forced as required. At the end of
the cycle, the system returns to its usual operating mode.
The Legionnaires' Disease protection treatment managed by the PAC's controller is fully programmable (frequency,
temperature threshold, treatment length).
This function requires the installation of the ambience terminal.
