INSTALLATION

PILOT

-C14-

MANUAL

Note:

The cycle starts by default at 22:00 with a set temperature of 60°C.

With the automatic summer/winter changeover function activated,
the pilot decides when to enact the changeover from one season
to another, independently from the choice made by the user via
the on/off button.

The pilot examines the exterior temperature for an extended period
of time (standby time) and uses the maximum exterior temperature
for heating («

TMAX.EXTER

», corresponding to parameter

P202

) as a

reference point:

- If the observed exterior temperature is continually above

the maximum temperature, the pilot switches to summer
mode.

- If the observed exterior temperature is continually below

the maximum temperature, the pilot switches to winter
mode.

This function can be activated by setting parameter

P204

yes

Parameter

P205

allows the adjustment of the length of standby

time observed by the pilot before the changeover from one season
to the other.

6.5.3.2 - Circulator pump speed

Heating circulation can be permanent or controlled by an ambient
temperature control.

If being controlled, the heating circulator will only be activated when
there is an ambient temperature request.

Control activated through parameter

circulation control functions

Diff erential between the set ambient temperature and the measured
ambient temperature to activate or deactivate a heating request.

Only applicable if an ambient temperature sensor is connected.

Controlled by parameter

6.5.3.1 - Ambient temperature sensor

hysteresis

6.5.3.4 - Anti-cold radiators

This function is only possible with an ambient temperature sensor.

Circulation is always controlled by the ambient temperature control.
When the set ambient temperature is reached, the pilot adopts
a lower set water temperature but continues to circulate so the
radiators do not become cold.

This function can be activated by setting parameter

P234

The set temperature can be lowered through parameter

P235

This function activates a cycle which raises the temperature in the
domestic hot water tank above the set temperature so as to eliminate
any bacteria. This cycle is carried out at regular intervals.

If the function is activated, the cycle will be carried out at the chosen
frequency and on the day of week chosen:

- Activation / choice of frequency at

P272

: deactived,

monthly, or weekly.

- Choice of day at

P273

: if the frequency is weekly, the

cycle will be carried out each week on the selected day.
If the frequency is monthly, the cycle will be carried out
on the fi rst day chosen in the month (ex. fi rst Monday of
the month).

Note:

If holiday mode is engaged for more than 3 days, an anti-

legionellosis cycle will run at the exiting of holiday mode.

6.5.4.2 - Anti-legionellosis protection

6.5.4 - Functions related to the production of

domestic hot water

Allows the operation of the heating circuit at the end of the domestic
hot water heating cycle when the tank’s temperature has been raised
suffi

ciently but before the cycle has been completed).

This function can be activated by setting parameter
