description.

FWTSKA - water temperature sensor for microprocessor controls model FWECS, FWEC1A/2A/3A

Directly connected to the microprocessor controllers FWECS and FWEC1A/2A/3A to measure the water temperature through the heat exchanger.

If the temperature registered is lower than 17 °C the unit works in cooling mode and the temperature range of the control panel will be referred to the cooling mode 

(19/31 °C); if the temperature registered is higher than 37 °C the unit works in heating mode and the temperature range of the control panel will be referred to the 

heating mode (14/26 °C). If the temperature registered is between 17 °C e 37 °C the control panel will disable the unit operation.

FWHSKA - Humidity sensor for FWECS, FWEC1A/2A/3A) microprocessor controller

Directly connected to the microprocessor controllers FWECS and FWEC1A/2A/3A, it enables the control of the heating element ventilation (if present, as support in 

heating mode) and the automatic cooling/heating changeover according to the water temperature.
