In the event of temporary absence over the weekend,
brief trips, etc. proceed as follows:
- Set the room thermostats to around 10°C
- Set parameter 2 to "10" or alternatively set the storage
heater thermostat to 10°C
By leaving the power supply on, as signalled by the
green LED flashing, and the fuel supply open the boiler
is protected.
The electronic controller has a
frost protection
function
that is also
active
in standby
The frost protection function has two levels:
- the first starts the pump
if the manifold temperature
≥
5°C, or alternatively, when
CH_type=1 and the outside probe is connected; if the
out. temp
≤
3°C (Par. 35=Frost_protection) the system
pump and the pump in the high temperature circuit are
started.
- the second starts the pump and the burner
if after 10 minutes the temperature in the manifold
≤
5°C, a burner is started at maximum output until the
temperature in the manifold
≥
20°C;
if after 10 minutes the temperature in the manifold
≥
5°C, while if CH_Type = 1 and the outside probe is con-
nected, and the outside temperature
≤
3°C, the pump
continues operating until the outside temperature
≥
3°C.
If the
CONDEXA PRO
boiler is not used for an extended
period, the following operations must be performed:
- Move the main system switch and the main boiler swit-
ch (1) to "off" and check that the green indicator light is
off (2).
- Close the fuel and water valves on the central heating
system.

In this case, the frost protection system is deac-
tivated. Empty the central heating and DHW
system if there is the risk of freezing.
