DO NOT BURN WET COAL
The thermostat connections on the back panel of the Stoker
Control are .25 inch male quick connect terminals. The mating
connectors (supplied) should be .25 inch female quick connector
terminals. The wire should be no smaller than 22 gauge.
The thermostat connections should only be connected across the
thermostat switch inside the thermostat unit. This switch is the type
which opens (turns off) when the set point temperature is reached,
and closes (turns on) when the room temperature falls below the
temperature. (This is the type supplied with the unit.)
The AC power cord should be the last connection made. The
power cord should be plugged into a 120 AC volt, 60 hertz, properly
grounded wall outlet. This wall outlet should also be capable of
handling 3 amps of current because this is the maximum amperage
this unit will draw.
Place the thermostat in a central
location. Do not place it in an isolated
room with poor air circulation.
Operation
basic Theory of Operation
After the stoker control is properly installed, operation of the stove may begin. The stove operation is
controlled from the thermostat. This means if the room temperature is cooler than the temperature set
on the thermostat, the stove will begin operation with the stoker control in the inactive state. Once the
room temperature reaches the thermostat set point temperature, the combustion blower and coal feeder
will turn off, but the distribution blower will still operate. At this point, the stoker control has taken control
of the stove's operation. The timer will continue to control the stove until the room temperature drops
below the thermostat set point temperature. At this time, the stove will operate constantly until the room
temperature reaches the thermostat set point again and the cycle repeats.
It should be noted that the timer adjustments do have a 0 minute position. The default conditions for
these adjustments set for 0 minutes are as follows: "on time= 0," off time= 0 unit will run constantly; "on
time" greater than 0," off time" 0, unit will run constantly; "on time" 0," off time" greater than 0, unit will
cycle on and off with the "off" time being the controlling timer. It is not recommended that the 0 minute
time be used on any of the adjustments. The 0 minute time is an invalid condition on the stoker control.
When the stoker control first takes control in the maintenance cycle, two timers are activated, the
"distribution blower" timer and the unit "off" timer.
The "distribution blower extend timer" is an off delay timer. This means after the combustion blower
and coal feeder turn off, the distribution blower will operate for the set period of time before turning off.
The stoker control timing range for this function is 0 minutes to 15 minutes.
