What to do if the display is blank on my Elan Thermostat?
If the display is blank, you should first check the circuit breaker and reset it if necessary. Also, ensure that the power switch at the heating and cooling system is turned on and that the furnace door is closed securely.
What to do if my Elan Thermostat cooling system does not respond when 'COOLING' appears on the screen?
If your cooling system isn't responding when 'COOLING' is displayed, check for 24VAC at the equipment on the secondary side of the transformer between power and common. If there's no voltage, investigate the cooling equipment. If 24VAC is present between the cooling terminal (Y) and the transformer common, the thermostat is functional; check the cooling system. Also, inspect for loose or broken wires between the thermostat and the cooling equipment.
Why is my Elan Thermostat heating equipment running in cool mode?
If your heating equipment is running in cool mode, check SW1 (Equipment Type) to ensure it is set to match the installed heating/cooling equipment.
Why is heat and cool both on at the same time with my Elan Thermostat?
If heat and cool are both on simultaneously, check SW1 (Equipment Type) to ensure it matches the installed heating/cooling equipment. Also, verify that the heating and cooling wires are not shorted together.
How to fix Elan Thermostat if the temperature settings do not change?
If the temperature settings are not changing, ensure that the heating and cooling temperatures are set to acceptable ranges. For heat, the range is 40° to 90°F (4° to 32°C), and for cool, it's 50° to 99°F (10° to 37°C).
Why is my Elan Thermostat fan not turning on when heating?
If the fan does not turn on when there is a call for heat, check System Setting 07 (Fan Control) to ensure the fan control is properly set to match the type of system.
Why is my Elan Thermostat heat pump issuing cool air in heat mode, or warm air in cool mode?
If your heat pump is issuing cool air in heat mode or warm air in cool mode, check System Setting 03 (O/B Operation) to ensure the reversing valve operation matches the heat pump.
Why is 'HEATING' not displayed on my Elan Thermostat?
If 'HEATING' is not displayed, ensure that the Control Setup is set correctly. Also, change the System Mode to Heat and set the temperature level above the current room temperature.
Why is 'COOLING' not displayed on my Elan Thermostat?
If 'COOLING' is not displayed, verify that the Control Setup is set correctly. Then, change the System Mode to Cool and set the temperature level below the current room temperature.
What to do if my Elan Thermostat heating system does not respond when 'HEATING' appears on the screen?
If your heating system isn't responding when 'HEATING' is displayed, check for 24VAC at the equipment on the secondary side of the transformer between power and common. If there's no voltage, investigate the heating equipment. If 24VAC is present between the heat terminal (W) and the transformer common, the thermostat is working; check the heating equipment. Also, inspect for loose or broken wires between the thermostat and the heating equipment.
