- Data Brochure
The Universal Reset Control 363 is a microprocessor based control designed to maximize the comfort and efficiency provided by a hydronic
heating system. The control automatically adjusts the boiler and mixed loop water temperatures that are delivered to the heating system
by using outdoor reset. For a mixing device, the 363 can use a variable speed driven wet-rotor circulator or a floating action driven mixing
valve. The 363 is capable of controlling an indirect Domestic Hot Water (DHW) storage tank and / or a setpoint load. The temperature of
individual zones can be controlled by connecting a conventional thermostat system or a tekmar Zone Control to the 363.
The 363 control includes a large Liquid Crystal Display (LCD) in order to view system status and operating information. The LCD and user
key pad are used to set the control’s adjustment and to monitor pump and boiler running hours, DHW tank temperatures, outdoor and
system high and low temperatures, boiler firing cycles, plus many other useful items.
Several energy saving features have been incorporated into the 363 such as Warm Weather Shut Down (WWSD), DHW post purge,
system setback, DHW priority, Morning Boost, Soft Start and an automatic differential for boiler control. The 363 also has a unique feature
that allows the control to supply heat to the mixed system from either the boiler or a thermal storage tank.
