Why should you install the Passiv Smart Thermostat with a heat pump?
Effortless comfort
By learning how a home heats up and cools down and optimising to local weather forecasts, the Passiv Smart Thermostat ensures a home is always the right temperature.
Lower bills
The Passiv Smart Thermostat can reduce a heating bill by 30% - the Energy Saving Trust verified that it increases a COP by 17% and it can optimise to time-of-use tariffs and solar PV too.

Simpler installs
By dynamically controlling a heat pump’s flow temperature, the Passiv Smart Thermostat removes the need to set a weather compensation curve and increases a heat pump’s efficiency.
Take the guesswork out of heat pump installations
With RS485 Modbus control, the Passiv Smart Thermostat removes the need to set…a weather compensation curve. Instead, it dynamically adjusts the flow temperature to ensure a heat pump runs with maximum efficiency.
The Passiv Programmer contains a built-in push-fit wiring centre to speed up heat pump installation. The Programmer is also used to commission the system in under two minutes without a smartphone or internet connection.
