If a used unit check under lid for a pressure hose no thicker than a pen , black or clear, look for splits or if disconnected reconnect

Hi niklok,

You have the thermostat hooked up incorrectly. Honeywell's directions are sometimes confusing. You should have power first to the thermostat and from the thermostat to the heater. You cannot have power running both to the thermostat AND the heater. That effectively assures a continuous ON situation. The black wire from the panel should be connected only to one lead from the thermostat.

If you need further instructions, please reply back with the number and color of wires coming from the panelboard and the number of heaters and the number and color of wires coming from your thermostat.

Thanks,

Handie Andie
