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.
