GENERAL CONSIDERATIONS
To ensure reliable long term operation, mount the boiler
control at a position in the appliance with a low ambient
temperature and a low radiation.
The boiler control should be externally fused.
High temperatures will affect product life.
NOTE 1.:
When first starting the boiler control has a self
check time of about 10 seconds.
NOTE 2.:
Electrical rating of connected controls should be
appropriate for the load that is switched by the
boiler control.
NOTE 3.:
Disconnect the boiler control from mains before
performing a dielectric strength test.
NOTE 4.:
When first starting, the control can be in the lock-
out condition; reset the boiler control.
NOTE 5.:
The flame connection pin of all types is
not
protected against electrical shock.
NOTE 6.:
An automatic return high limit thermostat can be
used.
Gold contacts for high limit thermostat are
required.
NOTE 7.:
The modulation function of the S4965 boiler
control units is checked during the start up safety
check. As a result the gas technical safety of the
appliance provided with a S4965 boiler control
unit can rely on the proper functioning of the
adjustable gas outlet pressure during ignition of
this boiler control unit.
This means that due to a safe ignition pressure
level, the safety time of the boiler can be
extended.
NOTE 8.:
Exhaust temperature protection may only be used
in non safety critical applications.
NOTE 9.:
Remote reset function may only be used in
applications where a maximum of five resets per
15 minutes is allowed.
WARNING
Honeywell is not responsible for damage and/or injury
due to mis wiring.
After installation boiler control can become wet due to
condensation.
Do not connect wet device to mains.
