MS4PMUHVT Multi-Stage Electronic Temperature Control with
Relay Pack
Description
The MS4PMUHVT Control is intended for
multi-stage temperature control applications.
This microprocessor based control offers
innovative features and state-of-the-art
technology to improve all your staged
temperature control applications.
Refer to the MS4PMUHVT Multi-Stage
Electronic Temperature Control with Relay
Pack Product Bulletin (LIT-125195) for
important product application information.
Features
• four enclosed, line voltage relays provide
direct control of motor loads without
additional relays
• 120/240 VAC power supply eliminates
need for separate transformers
• one control provides single-sensor
multi-stage control or dual-sensor reset
control, which reduces need for warehouse
or truck to stock multiple controls for similar
applications
• accepts A99 sensor signal, which is
suitable for a wide range of applications
• Surface Mounted Design (SMD)
technology assures high quality, reliable
components in a compact package
• keypad lock deters accidental changes to
parameter settings
• listed for use on refrigeration equipment in
accordance with Canadian and U.S.
National standards
Applications
This control is specifically designed for the
control of four-stage applications in the
following configurations:
• four cooling stages with common setpoint
• four heating stages with common setpoint
• four stages with deadband (two heating
stages and two cooling stages with
common setpoint)
• two independent sets of two dependent
stages (two heating stages and two cooling
stages with independent setpoints)
Repair Information
If the MS4PMUHVT Multi-Stage Electronic
Temperature Control with Relay Pack fails to
operate within its specifications, replace the
unit. For a replacement control, contact the
nearest Johnson
Controls® representative.
