WARNING: All MR4PMUHV controls are
designed for use only as
operating controls. Where an
operating control failure would
result in personal injury or loss
of property, it is the
responsibility of the installer to
add devices (safety, limit
controls) or systems (alarm,
supervisory systems) that
protect against, or warn of,
control failure.
These relay pack mounted controls provide direct
control of compressors up to 2 hp, electric heater
loads of up to 20 amperes, and evaporator fan loads
of up to 3/4 hp. The need for separate relays is
eliminated in these applications. In addition, the
MR4PMUHV controls combine the functionality of an
electromechanical thermostat, mechanical clock,
defrost termination device, and temperature readout
device with the accuracy of electronic technology.
Compressor Control Functions
Compressor Control: All MR4PMUHV controls
feature temperature based, On/Off control of a
compressor.
Anti-Short Cycle Delay: To avoid situations where
the compressor starts, stops, and restarts in a short
period of time, all models have a built-in anti-short
cycle delay. This feature determines the minimum
time between two subsequent On cycles of the
compressor.
Deep Freeze Cycle
From the front panel, the compressor output can be
forced On for a preset time to manually initiate a
freeze cycle. This feature is handy when loading a
cold room or a display cabinet.
Defrost Functions
Defrost Termination may be based on evaporator
temperature or time.
Defrost Mode: The MR4PMUHV control can perform
either hot gas or electrical defrost. During a hot gas
defrost cycle, both the compressor and defrost
terminals are energized. Hot gas is produced and
delivered to the evaporator coil via a solenoid valve
controlled by the defrost relay. During an electrical
defrost cycle, the compressor terminals are
de-energized and defrost terminals are energized to
turn on the electric defrost heater.
Manual Defrost: Initiating the manual defrost
sequence interrupts the current control state and
begins an immediate defrost cycle.
Fan Control Functions
The MR4PMUHV control can manage an evaporator
fan in one of two ways. The fan can either run
continuously or run only when the compressor is on,
and can be set to follow either time or evaporator
temperature based startup after defrost. Because the
MR4PMUHV control uses an SPDT relay for fan
control, a reversible fan motor can also be wired to
run in reverse to bring warm air over the evaporator
coils in a timed defrost application.
Alarm Management Functions
High and Low Temperature Alarm: The high and
low temperature alarms are set relative to the
setpoint. If the temperature exceeds the alarm values,
an alarm output relay is energized, and the display
flashes either +L or /R . High and low temperature
alarms are disabled during defrost and for 20 minutes
after the defrost cycle. Alarms are also disabled for
20 minutes after startup.
Alarm Time Delay: A time delay can be configured in
order to keep short-duration events from triggering
the alarm (i.e., door open).
Alarm Differential: An alarm differential can be set to
keep the alarm from cycling rapidly on and off.
Selectable Sensor Failure Mode: Temperature
sensor failure is indicated by an alarm. The controller
can be programmed for one of three sensor failure
modes: (1) the system shuts down, (2) the system
runs constantly, (3) the controller automatically starts
and stops the compressor based on the average
running times of the last four cycles.

Additional Features
Sensor Input: This series of controllers uses the
Johnson Controls A99 temperature sensor. The
controller allows you to program an offset of the
measured temperature for temperature
compensation or cable extension longer than 300 ft.
Adjustable Setpoint Stops: The setpoint stops
restrict the amount of change that the end user can
make to the setpoint. The end user cannot set a
setpoint value exceeding these limits.
Keyboard Locking: A sequence of key strokes
allows you to disable/enable modification of the
setpoint and other parameters. This prevents
accidental or unauthorized parameter modifications.
Self-test Procedure: This feature helps check
controller operation. After a key stroke sequence,
the control will cycle all outputs and test all LEDs.
Display Updating Time: The display update setting
provides an adjustable refresh rate for the
temperature readout. This feature is useful to avoid
displaying minor intermittent changes of
temperature.
Units of Measurement: Temperature units can be
selected as either degrees Fahrenheit or degrees
Celsius.
Display
The display has 2 LED digits and a minus (-)
indication. It displays a temperature range from
-40 to 99°F (-40 to 70°C) in increments of 1F° or C°.

arameter Definitions
Setpoint: This is defined as the relay cut-off.
The following parameters are described in the order
that they are displayed on the control.
+< Hysteresis (Differential): This is the difference
between the temperature at which the
compressor output is switched Off and the
temperature at which the output is switched On.
This is an absolute value relative to the setpoint.
Example:
Setpoint = 34°F (4°C)
Hysteresis = 2 degrees.
The compressor is switched On when the
temperature rises to 36°F (6°C), and is turned
Off when the temperature falls to 34°F (4°C).
// and +/ Low and high setpoint stop: The
setpoint value cannot be adjusted outside the
range defined by these parameters to avoid
improper setpoint setting by the user.
&& Anti-short cycle delay: This parameter prevents
the compressor from being turned On, Off, and
back On too quickly. The value set is the
minimum time between two subsequent On
cycles of the output.
Load Demand
Output Status
Anti-Short C
y
cle
Timer
&R Deep freezing time: This is the amount of time
that the compressor is forced On when the deep
freezing cycle is initiated.
$+ High temperature alarm: High temperature
alarm value relative to setpoint.
Example:
If the set point is at 34°F and the alarm value is
set to 5 degrees, the alarm is activated at 39°F.
$/ Low temperature alarm: Low temperature alarm
value relative to setpoint.
Example:
If the set point is 34°F and the alarm value is set
at -3 degrees, the alarm is activated at 31°F.
$G Alarm differential: Avoids alarm oscillation.
Example:
Setpoint = 34°F,
High temperature alarm = 6 degrees,
Alarm differential = 2 degrees.
When the temperature exceeds
34°F + 6F° = 40°F for a time greater than
parameter $W , the alarm is activated; when
temperature drops below 34°F + 6F°-2F° = 38°F,
the alarm is deactivated.
$W Alarm time delay: Delay between the detection
of a temperature alarm and the activation of the
alarm. This allows the control to ignore short-
term or transient alarm conditions during the
time delay. The controller also ignores
temperature alarms in the following cases:
•for 20 minutes after power On
•during defrost and for 20 minutes after the
defrost end
G) Defrost type: Selects the type of installation and
the way defrost is performed:
0 = Electrical defrost
(compressor off during defrost)
1 = Hot gas defrost
(compressor on during defrost)
G( Defrost end mode: Selects the defrost
termination type:
0 = Timer based; set with parameter GG
Note: Evaporator fan operation will restart
based on time
1 = Temperature based; set with parameter GW
Note: The defrost cycle always ends after
the time set for parameter GG
elapses.
GW Defrost termination temperature: Used only
when parameter G( =1. When the evaporator
temperature reaches this value, the defrost
automatically ends.
GL Defrost interval: This is the time between
two subsequent defrost cycles.
Note: When the defrost interval ( GL ) is 1 hour,
the maximum defrost duration ( GG )
cannot be set at more than 40 minutes.
GG Maximum defrost duration: The defrost cycle
will stop after this time, even if the defrost end
temperature has not been reached. Setting GG to

A—MR4PMUHV Electronic Temperature/Defrost Control with Relay Pack Product/Technical Bulletin 9
0 disables the defrost cycle in both manual and
automatic modes.
G&
Dripping time: After defrost is terminated, the
compressor is stopped for this length of time to
allow the evaporator to drip.
G8 First defrost after power-on: This parameter
delays the first defrost cycle after powerup. The
control will not initiate a defrost cycle for the
length of time set in this parameter. It can be
used to allow the system to reach operating
temperature before the defrost cycle is initiated.
Setting this parameter to 2) (Off) disables the
first defrost after power-on. Normally, the first
defrost occurs after the GL interval has elapsed.
G3 Display during defrost: Selects what
temperature is displayed during a defrost cycle:
0 = Last measured value before defrost cycle
1 = Setpoint
GU Display delay after defrost: During defrost
cycles, the ambient temperature is not displayed
(see parameter G3 ). The actual temperature is
displayed when it reaches the setpoint value or
after the time defined by this parameter.
L) Digital input function: The digital input (normally
closed) can be configured according to
installation requirements:
0 = The digital input is not connected
1 = If the contact is open for a time longer than
that set through parameter LG , the
compressor, defrost, and fan outputs are
switched Off, an alarm message (A1) is
displayed, and the alarm output is switched
On.
2 = Alarm function: If the contact is open for a
time longer than that set through parameter
LG , an alarm message (A2) is displayed and
the alarm output is switched On.
3 = Open door alarm: When the contact is open,
the fan is switched Off. If the contact is open
for longer than the time set through
parameter LG , an alarm message (A3) is
displayed, the alarm output is switched On,
and high and low temperature alarms are
disabled.
LG Digital input time delay: This is the time
between the detection of the digital input
opening and the enabling of the function
selected through parameter L) .
)) Fan operating function:
0 = Fan runs when the compressor runs
1 = Fan is always On
Note: The fan is always switched Off during
the defrost cycle.
)G Fan start-up delay (after defrost): The fan is
activated after this time even if the temperature
set through parameter )U has not been reached.
)U Fan start temperature after defrost end: This is
the evaporator sensor temperature at which the
fan is switched On after a defrost cycle.
Note: If the start temperature is not reached,
the fan is switched On after the time set
in parameter )G .
6) Sensor failure operation: This parameter
defines how the control functions after a
temperature sensor failure:
0 = Compressor remains On
1 = Compressor remains Off
2 = Automatic:
In automatic mode, the controller calculates the
average time the compressor was On during the
last four cycles. The controller then cycles based
on the average of these cycles. If a deep freezing
cycle or a defrost cycle occurred in the last four
cycles, they will not be taken into account nor will
the first cycle after the deep freeze or defrost.
6R Temperature sensor offset: This value is added
to or subtracted from the measured value to
compensate for possible field measurement
offset errors. To compensate for extra long
copper cabling use the following table:
Table 2: Wire Size and Cable Length
Wire Size and Cable Length
18 AWG 20 AWG 22AWG Offset
300-599 ft 190-374 ft 120-239 ft 1F°
600-899 ft 375-564 ft 240-349 ft 2F°
900+ ft 565+ ft 350+ ft 3F°
8Q Temperature units used: Determines
temperature units used for parameter settings.
0 = Celsius degrees
1 = Fahrenheit degrees
38 Display refresh rate: The temperature display is
refreshed at this rate. The display refresh rate
does not affect control performance.
