The temperature controller shall be electronic, microprocessor based with display working on 24V AC with 0-10V DC output. It shall be capable of accepting inputs from 3 temperature sensors. One temperature sensor for space temperature measurement and the other two temperature sensors for coil inlet and outlet water temperature measurements. The controller shall be capable of comparing the signals and selecting the lower output to prevent excessive water flow through coil. In case of BMS, controller shall accept 0-10V DC signal from BMS.
