Section A: General Operation

POWERING UP THE CONTROL
When the Mixing Control 362e is powered up, the control displays the control type number in the LCD for 2 seconds. Next, the
software version is displayed for 2 seconds. Finally, the control enters into the normal operating mode and the LCD defaults to
displaying the current outdoor air temperature.
CHARACTERIZED HEATING CURVE
The 362e uses a Characterized Heating Curve to calculate the
supply water temperature based on the outdoor air temperature.
The Characterized Heating Curve method of controlling the supply
water temperature takes into account the type of terminal unit that
the system is using. Since different types of terminal units transfer
heat to a space using different proportions of radiation, convection
and conduction, the supply water temperature must be controlled
differently. Once the control is told what type of terminal unit is used,
the control varies the supply water temperature according to the
type of terminal unit. This improves the control of the air temperature
in the building.
EXERCISING (EXERCISE)
The 362e has a built-in pump and valve exercising function. The exercising period is adjustable and comes factory set at 70
hours. If a pump or valve output on the control has not been operated at least once during every exercising period, the control
turns on the output for 10 seconds. This minimizes the possibility of a pump or valve seizing during a long period of inactivity.
The 362e ensures that the mixing valve operates over its entire range at least once each exercising period.
Note: The exercising function does not work if power to the control, valves or pumps is disconnected.
FLOATING ACTION
A floating action actuator motor is connected to the 362e on the Pwr Mix, Opn, and Cls
terminals (8, 9 and 10). The 362e pulses the actuator motor open or closed to maintain
the correct supply water temperature at the mix sensor when there is a Mix Demand.
The mixing valve that the actuator is connected to can be either a 2-way, 3-way or 4-
way valve. A visual indication as to whether the control is currently opening or closing
the mixing valve is displayed in the LCD with the words Open and Close. Also, a visual
indication of the current position of the valve is displayed in the LCD in the form of a
segmented bar graph.
