tekmar Mixing Control 365

Control Description The Mixing Control 365 is a microprocessor-based mixing outdoor reset control that operates a permanent capacitor, impedance protected or equivalent pump at varying speeds and also operates a 4-20 mA output. A tekmar Indoor Sensor, RTU or Zone Control can be connected to the 365 in order to provide indoor temperature feedback from single or multiple zones. The 365 can also regulate the minimum boiler return temperature to help prevent boiler thermal shock or flue gas condensation. The 365 has a night setback input and WWSD for the system pump and boiler demand.
