Binary Input Response
Binary Input Function
allows the user to select how
the control responds to a binary input (switch) if the
binary input contacts are open for a time (minutes)
longer than the
Binary Input Time Delay.
Additional Features
The MS4PMUHVT control uses several other
settings to control specific features:
Keyboard Locking
disables/enables change of
the setpoint and other functions, reducing
accidental or unauthorized changes of the
control settings.
Self-test Procedure
initiates a cycle of all
outputs and tests all LEDs. See
Initiating a
Manual Self-Test
.
Dual Sensor Temperature Reset
resets the
setpoint based on the difference between the
Auxiliary Temperature Sensor (ATS) and the
Setpoint to provide energy savings. See
Temperature Reset
.
For additional information about control functions
and how to program them, see
Programming the
Control
and
Control Functions.
Control Module Front Panel
The control module has an LED display and buttons
for entering programming information and activating
various features.
The display has three LED digits and a minus
indicator. It displays a temperature range from
-40 to 176°F (-40 to 80°C) in increments of 1F° or
C°. The display also features three relay status
LEDs.
LED 1 indicates that the Stage 1 Relay is
energized.
LED 2 indicates that the Stage 2 Relay is
energized.
LED 3 indicates that the Stage 3 Relay is
energized.
