I'm trying to replace an old honeywell thermostat attached to a Tiranco Heatmaker with a new programmable thermostat, RITETEMP. I have only two wires which are not labeled(one black one white). The new thermostat has all kinds of wire ports with different letters

If anyone knows how to attach which wires to attach where please let me know

THANKS!

What model of t-stat is it? If its digital and doesn't run on batteries you need to add a wire or get a different t-stat.
