NOTES
FACTORY WIRING
REPLACEMENT WIRE MUST BE SAME SIZE AND TYPE OF
1
INSULATION AS ORIGINAL (AT LEAST 105° C). USE COPPER
CONDUCTORS ONLY. USE N.E.C. CLASS 2 WIRE FOR ALL
LOW VOLTAGE FIELD CONNECTIONS. USE COPPER
CONDUCTORS FOR UNIT SUPPLY POWER.
FOR 208V SUPPLY POWER, MOVE WIRES FROM THE 240V
2
TAP TO THE 208V TAP.
3
FOR DEHUMIDIFICATION, CONNECT A 24VAC DEHUMIDISTAT
FIELD WIRING
THAT OPENS ON HUMIDITY RISE TO GRAY WIRE FROM THE
VSTB AND TO R ON IIC; SEE INSTALLATION INSTRUCTIONS
FOR DETAILS. CUT 'HUM' JUMPER ON VSTB.
