CONNECT THE WIRES
Using the caps supplied (2), connect the wires of the MAESTRO thermostat to those of the heating system and
power supply according to the corresponding connection diagram (2 or 4 wires). Tighten the caps onto the wires to
ensure the connection is secure. Then place all the wires inside the electrical box.
NOTE
: If the electrical wires are aluminum, use
CO/ALR connectors instead (not supplied).
NOTE
: Since thermostat wires do not have polarity,
the way they are connected is not important.
