Do we have a product to help customers with this control, since it is obsolete and uses a 100k sensor?
The product uses a relay pack that is separate for the control portion. Any substitute thermostat will need to be re-wired. Once the wiring in the wall is changed, a thermostat that has an ambient, room mode, or has a "regulator" function can be used. The current OJ thermostat offerings do not support the use of a 100k floor sensor
See the data and wiring sheet that is attached.
