Mode is locked out based on outside air temperature.
Change configuration parameter H Lock to value 120°F (49°C) to by-pass

Start the Fan by forcing the Fan ON mode.
Put a jumper across terminals RH and W1. The heating should come ON. If it
does not, verify wiring and check if a jumper is required between RC and RH.
