Working models
This page covers the Itho Daalderop units supported by non-CVE and CVE add-ons.
- CVE ECO 2 (this unit is also sold by the brand 'Heatrae Sadia' in the uk)
- CVE ECO RFT (SE/SP, HE/HP)
- CVE-S ECO (SE/SP, HE/HP)
- CVE-S OPTIMA package with built-in CO2 sensor. CO2 sensor usable but an extra long pinheader needs to be soldered on the add-on)
- HRU 200 ECO (also sold as 'Elektrodesign EHR 140 Akor BP' and 'Heatrae Sadia Advance Plus')
Older CVE (before 2010?) Itho models do not have the needed interface (2x4 pinheader) but a single strip if pins. These models are not compatible.
- HRU eco fan
- HRU 350
- DemandFlow
- QualityFlow
- HeatPump WPU
- AutoTemp
- HRU 300
Most important, look for the 2x4 pin interface on your main ITHO PCB (encircled in red on the image below). If this interface is present it is likely the module will work.
