Do any Ritetemp thermostats also control humidity?

Yes, you can control humidity by using a Ritetemp thermostat equipped with a built in humidistat (models 8082C and 8085C).
If you have an existing humidifier, with an external humidistat, and wish it to be active only when the thermostat is switched to HEAT, connect the power wire (R) from your humidistat to the B terminal of the thermostat.
When the mode switch is put in HEAT, the B terminal is powered from the RH terminal, which will power the external humidistat. The humidistat will then operate independent of the thermostat settings. When the thermostat is switched to OFF or COOL, the external humidistat will be off.
If you wish the external humidistat to be active only when the heat is running, connect its power terminal to W instead of B.
If you wish the external humidistat to be always active, connect its power terminal to RH instead of B or W. It will then operate independent of the thermostats mode switch.
See page 18 in the Professional reference guide for more details.
