Thanks for info but does it matter how it is hooked up in thermostat R or W. I guess not but what about lugs on stove.

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.

on the Thermostat

1. Loosen screw terminals, insert wires into terminal block, then re-tighten screws.
2. Push excess wire back into the wall opening.
3. Plug the wall opening with nonflammable insulation to prevent drafts from affecting thermostat operation.
Wiring
NOTES
R & Rc terminals (T87N)
In single-transformer system, leave metal jumper in place between R & Rc. Remove metal jumper if two-transformer system.
Heat pump systems (T87N)
If wiring to a heat pump, use a small piece of wire (not supplied) to connect terminals W and Y.
Wire specifications
Use 18-gauge thermostat wire. Shielded cable is not required.
Wallplate installation
Terminal Designations—T87N
W Heat relay.
Y Compressor contactor.
G Fan relay.
O Heat pump changeover valve energized in cooling.
Rc Cooling power. Connect to secondary side of cooling system transformer.
R Heating power. Connect to secondary side of heating system transformer.
B Heat pump changeover valve energized in heating.

Nothing is polarity sensitive...does NOT matter. :)

A t'stat in just a simple switch for on or off operation. ;)
