Table 3. Honeywell Control to Honeywell S8910U Cross Reference.
a
The S8910U and the original control lockout times are different. The S8910U lockout time is within the design tolerance
lockout time of the original control.
b
The lockout time of the S8910U is shorter than the original control. Be sure to observe the appliance operation under a
variety of input conditions to assure reliable operation.
REVIEW THE INSTALLATION
WARNING
FIRE OR EXPLOSION HAZARD.
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY, OR DEATH.
Follow these warnings exactly:
1. Review the installation as outlined in this
section.
2. Plan for frequent maintenance as described in
the Maintenance section.
When hot surface ignition systems are used on central
heating equipment in barns, greenhouses, and commercial
properties and on heating appliances such as commercial
cookers, agricultural equipment, industrial heating
equipment and pool heaters, heavy demands are made on
the controls. Special steps can be required to prevent
nuisance shutdowns and control failure due to frequent
cycling, severe environmental conditions related to
moisture, corrosive chemicals, dust or excessive heat.
These applications require Honeywell Home and Building
Control Engineering review; contact your Honeywell Sales
Representative for assistance.
Review the following conditions that can apply to your
specific installation and take the precautionary steps
suggested.
Frequent Cycling
These controls are designed for use on appliances that
typically cycle only three to four times an hour during the
heating season. In year-round applications with greater
cycling rates, the control can wear out more quickly.
Perform a monthly checkout.
Water or Steam Cleaning
If a module or gas control gets wet, replace it. If the
appliance is likely to be cleaned with water or steam, cover
the controls and wiring to protect from water or steam flow.
