How It Works
1/2
Hydrostat 3200
FORCE E boilers are equipped with Hydrostat 3200 and Honeywell S8610M
Ignition module. Hydrostat 3200 contains features such as high limit switch,
LWCO and circulator relay. Energy is saved by using a thermal target feature
which adjusts boiler target temperature depending on heat required.
Honeywell S8610M provides ignition control.
Dual sensor for boiler temperature control and protection against potentially
damaging low water conditions in boiler. In event of low water condition,
“LOW WATER” LED will turn on and control will shutdown burner. Can be
configured for auto reset or manual reset LWCO.
When thermostat calls for heat, Hydrostat 3200 starts system circulator,
checks safety limits, and activates vent damper.
When vent damper is opened completely, ignition module opens pilot valve
and activates ignition spark.
Honeywell S8610M
Ignition Module
Ignition module will sense pilot flame. Once pilot flame is established,
ignition module opens gas valve and main burners will ignite.
When thermostat is satisfied, ignition module turns off gas valve, deactivates
damper, and deactivates circulator.
Hyrdostat 3200 indicates boiler status. Indicator lights provide assistance
with troubleshooting. See Hydrostat 3200 installation instructions and
operating manual for more information.
Honeywell S8610M indicator lights provide assistance with troubleshooting.
See Table 10-4 for more information.
3
Draft Hood
Provides adequate dilution air and ensures proper draft for boiler operation.
Blocked Vent Switch
If vent becomes blocked, switch will open (requiring manual reset) and
cause burners to shut down.
4
Flame Roll-Out Switch
If flames roll out of burner tubes, switch will open (requiring replacement)
and cause burners to shut down. If switch trips, determine cause of flame
roll-out.
5
Gas Valve
Regulates gas flow to boiler.
6
Pilot
Provides ignition source for burner lighting.
7
Vent Damper
Closes during off cycles to reduce heat loss from house to vent.
