❈ In case of loose screws or insufficient contact between the terminal and the wire, thermostat may not function
properly.
❈ When the power is off on the Thermostat, check the connection between the Thermostat and Terminal Block.
❈ Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small head will strip
the screw head and make tightening difficult.
❈ Over-tightening terminal screw may cut wires or cause irreparable damage to thermostat.
