Questions

Questions about ELIOS parts.

Where do I find the model number?

On the indoor unit’s rating label. Send us a photo if in doubt: we will find the right part.

Does my ducted unit or cassette need a Wi-Fi controller?

Not the R-454B ones: GDHRA ducted units and GKHRA, GQHRA24 and GOHRA cassettes already come with the KJRSAALW1 wired Wi-Fi controller.

Which thermostat for an ELIOS central heat pump?

ELIOS lists the KJRSAALN1, the KJRSAALW1 (Wi-Fi) and the ST1S42RW1 smart thermostat for EAHMA units; for coils, the KJRKAALW1 or the ST1S42RW1, with the coil interface.

Does the ST1S42RW1 thermostat work with a wall unit?

On an EMC or EBC, per the ELIOS brochures, with the MI3C1 mini interface and a 24 V supply. Some functions are not available through this thermostat.

Why are some parts “to confirm”?

Because no ELIOS document read publishes their compatibility list (jumper bar, Doctor Smart tool, and the LI2C1 large interface outside multi-zone). We confirm with the full model number.

Can you install the part?

Yes. Controllers, interfaces and heater kits involve wiring: AirGreen installs them, RBQ licence 5645-9605-01, subclass 16 (electrical).
