Wiring the New Thermostat
1. Disconnect Energy
Earlier than touching any wires, flip off the facility to the oil burner tank on the foremost electrical panel.
2. Take away the Previous Thermostat
Loosen the screws that maintain the previous thermostat in place and disconnect the wires from the terminals.
3. Establish the Wires
Utilizing a multimeter or continuity tester, determine the road (L), load (L1), and impartial (N) wires. Shade codes could range, however sometimes:
- Purple or Black: Line
- White: Impartial
- Blue or Black: Load
4. Join the New Thermostat
Join the wires to the corresponding terminals on the brand new thermostat:
- Line (L): Normally marked "L" or "Line"
- Load (L1): Normally marked "L1" or "Load"
- Impartial (N): Normally marked "N" or "Impartial"
5. Safe the Thermostat
Mount the brand new thermostat on the wall and tighten the screws to safe it.
6. Step-by-Step Wiring Particulars:
a. For a Single-Stage Oil Burner:
