The heating system can freeze when not in operation.
▶ Leave the heating system on if the outside temperature is below 0 °C.

protection can only be guaranteed where outdoor weather-compensated 
controls are used.

▶ Correct any faults immediately.

Product details

Room temperature-dependent controller

 for heating systems with one 

unmixed heating circuit

Zone controller

 for one unmixed heating circuit with a wiring module, and max. 

4 heating circuits in systems without alternative Building Management Systems 
or miscellaneous high level controls. For additional time control of the zones a 
Sense II can be used instead of a Sense I (combination of 1 Sense II and a 
maximum of 2 Sense I with a wiring module).

Room thermostat

 in systems with higher-level control (e.g. Greenstar Sense II 

with max. 4 heating circuits)

For heat sources with 2-wire BUS, e.g. EMS (Heatronic 3®) and EMS 2

Must be used in conjunction with a suitable compatible time control

The Sense I may not be used as a controller for heat sources with an external 
cylinder primary pump. If an external cylinder primary pump is installed, the 
Sense I may only be used as a room thermostat.

Use in conjunction with Worcester FX controls FR10, FW100, FR110 is not 
possible.

Some settings may not be available, depending on the connected heat source.
