Q: Can the power of Gialix be reduced ?

Refer to your GIALIX manual. Power adjustment can be done either by wiring inside the boiler, by setting in the control system, or by wiring + setting. Instructions for this operation are specific to each model of GIALIX and should be carried out by a qualified professional. By setting: use parameter 22 (refer to the manual). Attention! In order to supply the boiler with a reduced section cable and protect it with a lower-rated circuit breaker, reducing power by setting alone is insufficient: it is imperative to disconnect part of the heating elements (see technical manual).

Question 1

Using an aquastat or a hot water sensor ?

Accepted Answer

It's preferable to connect a hot water sensor rather than a hot water aquastat: with a hot water sensor, there's frost protection monitoring for the hot water tank.

Question 2

Can we produce hot water for sanitary use ?

Accepted Answer

YES

Several options are available in the GIALIX range.

Question 3

Can a radiant floor heating system be powered ?

Accepted Answer

OUI

Gialix is designed to directly supply an underfloor heating circuit without a mixing valve. It is sufficient to set its maximum temperature below 50°C. The boiler even includes the safety aquastat at 65°C with manual reset, which is mandatory.

Question 4

Can we supply a radiator circuit ?

Accepted Answer

YES

This is the default configuration of the boiler from the factory.
Preferably install an outdoor sensor (ref. 710157) to automatically adjust the boiler's departure temperature based on outdoor conditions.

Question 16

What thermostat can I connect ?

Accepted Answer

The electric boiler can accept any type of dry contact room thermostat (also known as potential-free or On/Off contact), provided that it is not of the "chrono-proportional" type.
- Auer offers 3 thermostat models (TA - Room thermostat ref. 710043, TH Room thermostat with clock ref. 710044, and TH RNC Wireless room thermostat non-chrono-proportional ref. 710172)
It connects to the boiler with 2 wires on terminals 1 and 2. If there is no room thermostat, no bridging is required.
It can be wireless with radio frequency transmission.
It can incorporate a clock. To be recognized by the electric boiler, simply set the control (parameter No. 04 = 01).

Question 17

The circulator is stuck, how do I unstick it ?

Accepted Answer

The circulator blockage is due to impurities present in the heating circuit water (sludge, metallic particles, limescale, etc.) and prolonged power outage of the boiler.

To prevent blockage, it is imperative to leave the boiler powered on in standby mode during extended periods of absence to allow it to perform the daily degreasing cycles controlled by the regulator.

To unblock the circulator:

Check that the circulator is powered and that it confirms a blockage (red + yellow lights illuminated).
To unblock the circulator, use a PH2 type crosshead screwdriver. Insert the screwdriver into the central hole of the front plate and push the screw (approximately 5mm stroke) to engage it in the degreasing position.
While holding the screw pushed, turn alternately left and right.
When the circulator is unblocked, the red light turns green.

Question 18

In case of a breakdown, who should you contact ?

Accepted Answer

In case of a breakdown, contact your installer.
Only a qualified professional is authorized to intervene on your appliance safely.
Limit your intervention on the appliance to switching it on/off, cutting off power, or simple adjustments that you are familiar with.
If it is a breakdown with an error message on the product's screen, use this code and the table of fault codes (available in the manual of your appliance or in the technical support section by product on the website below) to inform your installer about the nature of the problem.
You can also use this table of fault codes to determine whether this error causes a shutdown of the operation.
