Relay Configurations

Rly xx: Not Used

Use < Or > To Change

The following 20 screens allow you to set the 4 relays on the MUA II

Controller board and up to 16 additional relays when relay expansion

board(s) are used.

The ﬁ rst relay on the controller is always reserved for the Supply Fan.

The remaining 4 relays on the main board and the additional 16 relays

on the expansion relay boards can be conﬁ gured by pressing the left or

right arrow key to change the relay to the desired conﬁ guration.

Available options are

• Not Used • Gas Re-Heat

• Heat Stage • Exhaust Fan

• Cool Stage • Pre-Heater

• Warmup Mode • External Heat

• Rev Valve

The MUA II Controller does not require you to start conﬁ guring your

Heating or Cooling Stages ﬁ rst nor does it require that you utilize con-

secutive relays until all Heating or Cooling Stages have been deﬁ ned.

This method allows the greatest ﬂ exibility in the ﬁ eld, but it requires

close attention to the wiring of the Heating and Cooling Stages to prevent

incorrect and possibly harmful operation. The controller assumes that

there will only be one relay conﬁ gured for Hot Gas Reheat and one relay

for External Heat Enable, although it doesn’t prevent multiple relays

from being selected.
