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.
Product details Product data for energy consumption The specified product data correspond to the requirements of the EU Regulation No. 811/2013 which supplements ErP Directive 2010/30/EU. The class of the temperature controller is required to calculate the room heating energy efficiency of an integrated system and is for this reason incorporated into the system data sheet.
Product details Technical specifications Technical data Measurements (W × H × D) 82 × 82 × 23 mm Rated voltage 10 – 24 V DC Rated current 4 mA BUS interface EMS/EMS 2 (2-wire BUS) Control range 5 – 30 °C Permiss.
Old electrical and electronic appliances 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). The control of the zone temperature is thus achieved in the same way as in the case of the function as room temperature-dependent controller with adjusted flow temperature control.
