4.Remove the jumper across T and T1. The actuator should drive fully closed.
5.Return EconoMi$er IV settings and wiring to normal after completing troubleshooting.
G.EconoMi$er IV Troubleshooting Completion
This procedure is used to return the EconoMi$er IV to opera- tion. No troubleshooting or testing is done by performing the following procedure.
1.Disconnect power at TR and TR1.
2.Set enthalpy potentiometer to previous setting.
3.Set DCV maximum position potentiometer to previ- ous setting.
4.Set minimum position, DCV set point, and exhaust potentiometers to previous settings.
5.Remove
6.Remove 1.2
7.Remove jumper from TR to N.
8.Remove jumper from TR to 1.
9.Remove 5.6
10.Remove jumper from P to P1. Reconnect device at P and P1.
11.Apply power (24 vac) to terminals TR and TR1.
