CH16 with MV Air Handler and 3H2C TStat

Notes:

1. Y2 Terminal on A/H control board must be connected for full CFM and applications requiring 60 second blower off delay for SEER enhancement.
2. Move HUM STAT jumper on A/H control board to YES position if humidistat or communicating control is used.
3. For heat pump applications - set MODE jumper on A/H control board to HP position.
4. To change the quantity of heat during HP defrost cycle - reverse connections at W1 and W2 on A/H control board.

** Optional dehumidification humidistat switch contacts open on humidity rise.

*** Not all thermostats have E or AUX terminals

• All E/Aux/W2 signals must go to the CH16 first on "W"
• You may need to put a jumper in E/Aux/W2 at the T-Stat (follow T-Stat manufacturers manual)
  • The CH16 will energize backup heat on "W1out"
  • After 15mins of backup heat, the CH16 will engage "W2out"
  • Do NOT jumper "W1out" and "W2out"
