Hi, My new honeywell is showing me a fault 53 lock out switch. Can anyone help me clear this fault?
Typical of Honeywell, the fault codes are not listed in the flame safeguard control manual, but with the S7800 keyboard display module. The S7800 manual can be downloaded here: http://customer.honeywell.com/techlit/pdf/PackedLit/65-0090.pdf
