CTSmall heat pump controller

CTSmall is a smart heat pump controller that lets you manage temperature and power remotely via app or SMS. It works with most heat pumps from leading manufacturers, and with the CTSmall extension box you can control two relays for water heaters or floor heating.

Key features include an event system to trigger actions on the extension box or heat pump, support for 35+ brands, alarm output, power guard, and up to four emergency numbers. All settings are configurable from the app. Requires a CTSmall controller from Climatech.dk. More information at CTSmall.eu.
