5.11 TM – MINIMUM WATER TEMPERATURE THERMOSTAT
Bimetallic thermostat with fixed set point, to be used in heating only. It is factory
mounted or, upon request, supplied separately as a kit.
Functions:
• during heating operation, it prevents the fan from starting if the coil temperature
has not reached the set point temperature
Technical features:
• installation position: clipped to the coil fins
• set point temperature: 42 °C ± 3 °C
• differential: 10 °C
• rating of contacts: 3 A - 250 V~
5.12 WS – WATER SENSOR
3m long NTC sensor (10K, 25°C), requested for the automatic S/W switch when
a fancoil unit is controlled by a regulator with microprocessor or OMNIBUS, in
a 2 pipe system, for both heating and cooling operation. The Summer/Winter
changeover works as follows:
• WS combined with CER00, CER20, CER30/B, CEL00, CEL20, CEL30/B
Summer: water temperature < 17 °C = cooling on
water temperature > 19 °C = cooling off
Winter: water temperature > 32 °C = valve open
water temperature < 30 °C = valve closed
water temperature > 35 °C = fan on
water temperature < 33 °C = fan off
• WS combined with CER10/B, CER11, CEL10/B, CEL11, CER31, CEL31
Summer: water temperature < 11 °C ± 1 K = cooling on
water temperature > 14 °C ± 1 K = cooling off
Winter: water temperature > 40 °C ± 1 K = heating on
water temperature < 30 °C ± 1 K = heating off
The water sensor is not suitable when 2 way valves are mounted on the unit (i.e.: H2A2 or J2AM).
