Fan-Coil Thermostat T6590A
Description
Electronic thermostat T6590A for heating and / or cooling control in ventilation systems.
T6590A provides automatic control of servomotor / thermoelectric drive valves and fan speed in 2-pipe fan coil systems. In 2-pipe systems, the control of an auxiliary electric battery (if installed) is also ensured.
Modern design with large display and lighting;
P + I control form (proportional + integral) with on / off actuation signal
display information: summer / winter operating mode, fan speed, reference / ambient temperature
automatic or manual fan speed control
built-in sensor and optional remote or in the air duct
digital input for activating the economy mode from the open window contact, card, or centralized external contact, the EPROM memory retains the settings in the absence of voltage
"installer settings" mode that allows you to adjust the parameters to suit the application
economical temperature for both summer and winter operating modes (temperature rises or falls).
