Wiring Diagrams
Typical condensing unit and heat pump wiring diagrams are provided in figures 12 and 13. Some modifications to certain units may be necessary.
Connect the EDA unit with the indoor and outdoor units, and to the thermostat. Be sure the outdoor sensor is installed and connected to the SignatureStatt thermo- stat’s outdoor sensor terminal block. Table 3 shows the re- quirements for control wiring.
