T606MSx-4 and T606MSx-4+PIR Series Multi-Stage Temperature and Humidity Controllers
Installation Instructions

Wiring
When an existing controller is replaced, remove and
label the wires to identify the terminal functions. When
a T606MSx-4 or T606MSx-4+PIR Series Controller is
replaced, simply remove the old screw terminal blocks
and reinsert them onto the PCB of the replacement
controller.
To wire the controller:
1.
Strip the ends of each wire 1/4 in. (6 mm) and
connect them to the appropriate screw terminals as
indicated in Figure 5.
2.
Carefully push any excess wire back into the wall.
Note:
Seal the hole in the wall with fireproof
material to prevent drafts from affecting the
ambient temperature readings.
3.
Reinsert the screw terminal blocks onto the PCB. If
multiple wires are inserted into the terminals, be
sure to properly twist the wires together prior to
inserting them into the terminal connectors.
4.
For PIR models, carefully reattach the PIR
connector to the PCB.
5.
Reattach the controller cover to the mounting base
(top side first).
6.
Use a Phillips-head screwdriver to install the
security screw on the bottom of the controller cover
if desired. The security screw comes packaged
separately in a plastic bag with the controller.
!
CAUTION: Risk of Electric Shock.
Disconnect power supply before making
electrical connections to avoid electric
shock.
!
CAUTION: Risk of Property Damage.
Do not apply power to the system before
checking all wiring connections. Short
circuited or improperly connected wires
may result in permanent damage to the
equipment.
IMPORTANT:
Make all wiring connections in
accordance with local, national, and regional
regulations. Do not exceed the electrical ratings of
the T606MSx-4 or T606MSx-4+PIR Series
Temperature and Humidity Controller.
