Thermostat question

[MMarmino]

Good evening everyone, I'm sure it's been asked before but I need help setting up a thermostat for my outdoor wood boiler. I have a heat exchanger with blower and would just like to set up a thermostat that I can set at a temperature and have the fan come on and go off, no thermal coupler . I bought a Honeywell like the one pictured. I'm not for sure if this is the correct one. Thanks for any help.

Unless you have a 24v motor on your air handler, or a relay. you would be better off with line voltage thermostat.
