Do not use flanges on control models with 3/4 in. inlet
and 3/4 in. outlet. On models with 1/2 in. inlet and
3/4 in. outlet, use flanges only on the 1/2 in. inlet side.
Heavy demands are made on the controls when
intermittent pilot 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.
Special steps may 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 follow the precautions suggested.
Frequent Cycling
This control is designed for use on appliances that
typically cycle three to four times an hour only during the
heating season. In year-around applications with greater
cycling rates, the control can wear out more quickly.
Perform a monthly checkout.
Water or Steam Cleaning
If a control gets wet, replace it. If the appliance is likely to
be cleaned with water or steam, protect (cover) the
control and wiring from water or steam flow. Mount the
control high enough above the bottom of the cabinet so it
does not get wet during normal cleaning procedures.
High Humidity or Dripping Water
Dripping water can cause the control to fail. Never install
an appliance where water can drip on the control. In
addition, high ambient humidity can cause the control to
corrode and fail. If the appliance is in a humid
atmosphere, make sure air circulation around the control
is adequate to prevent condensation. Also, regularly
check out the system.
