USE 18 AWG WIRE MINIMUM. TO MINIMIZE
INTERFERENCE PROBLEMS:
USE SHIELDED WIRE ON ALL ANALOG INPUTS
AND OUPUTS. DO NOT RUN 0-10 VOLT DC
SIGNAL WIRING IN THE SAME CONDUIT AS
LINE VOLTAGE WIRING OR WITH WIRING
THAT SWITCHES HIGHLY INDUCTIVE LOADS
SUCH AS CONTACTOR AND RELAY COILS.
GROUND ONE END OF THE DRAIN (SHIELD)
WIRE.
WHEN 0-10 VOLT DC SIGNAL WIRING MUST
CROSS CLOSE TO CABLE OR NONMETALLIC
CONDUIT CONTAINING LINE VOLTAGE
WIRING OR WIRING THAT SWITCHES HIGHLY
INDUCTIVE LOADS, IT MUST CROSS
PERPENDICULAR (90 DEGREES) TO IT.
KEEP THE 0-10 VOLT DC SIGNAL WIRING AS
SHORT AS POSSIBLE.

DUCT. SENSOR MUST BE INSTALLED DOWNSTREAM OF HEATER WHERE
IT CANNOT “SEE” ANY HEATING ELEMENTS AND WHERE SUFFICIENT
MIXING OF DISCHARGE AIR OCCURS. USE 18 AWG SHIELDED WIRE. DO
NOT RUN SENSOR WIRING IN THE SAME CONDUIT AS LINE VOLTAGE

ALL FIELD INSTALLED SENSORS SHOULD BE WIRED TO THE
CONTROLLER FOR FACTORY TESTING WITH TEMPORARY
WIRING AND LEFT IN THE UNIT AFTER TEST. TEMPORARY
WIRING SHOULD BE REMOVED FOR PERMANENT
INSTALLATION DURING UNIT INSTALLATION. LABEL
SENSORS PER THE WIRING DIAGRAM.
To wall mount the
Equipment Touch, remove
the factory installed cable
and wire +24VAC to TB4 “K3”
and wire Gnd to TB4 “K4”. If
there is a ZS sensor installed,
wire Rnet+ and Rnet- to the
ZS sensor Rnet+ and Rnet-
terminals. Otherwise, wire to
TB5 Rnet+ and Rnet-
