Mixing Control 362
The Mixing Control 362 is a microprocessor based control with two distinct operating modes.
MODE —1— allows the control to provide a reset mixed supply water temperature to a heating system based on outdoor air temperature.
Multiple zone temperature controls can be achieved by using either a conventional thermostat system or by using tekmar Zone Controls
attached to the 362. For single zone heating applications, a single Room Temperature Unit (RTU) can be connected directly to the 362
for zone temperature control.
MODE —2— allows the control to provide a single zone of snow melting. With the addition of a Snow Melting Kit 092, the 362 can
provide slab temperature control and slab ΔT protection. The melting mode is initiated manually either with a demand signal or from the
Snow Melting Kit enabling device.
The 362 incorporates a large Liquid Crystal Display (LCD) in order to provide system status and operating information. The same LCD
is used when setting up and installing the control. Standard features for both modes of operation include boiler return protection,
intelligent boiler operation, Warm Weather Shut Down (WWSD), and pump exercising. As well, with the addition of a new Monitor
feature, it is now possible to track pump and boiler running hours, boiler cycles and high and low sensor temperatures. The 362 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.
Note:
Mixing demand must be
powered with 20 to 260
V (ac) before the mixing
valve is able to open and
the boiler is able to fire.
