Insufficient or no heat
• Check that the heat generator is functioning properly.
• Plugged air filter or coil. Refer to maintenance section for filter care and coil cleaning.
• Air in heating loop - purge system.
• Inlet and outlet connections to ecosmart are backwards - reverse connections.
• Supply water temperature set too low or heat generator is not supplying water at the
specified setting.
• Restrictions on heating loop - remove restrictions, check if valve is stuck, isolation valves
could be too restrictive or left partially closed after purging, or a closed valve.
Cold water at hot faucet
When the heat source is a water heater, the most probable cause is reverse flow through the
heating loop from a stuck check valve - repair or replace valve.
Fan runs for cooling but not for heating
The room thermostat may be connected improperly. Refer to Electrical section or wiring
schematic on ecosmart for proper installation.
Heating during standby mode
Probable cause is thermal siphoning.
