Greenhouse heaters

i am currently using a thermostat ic plug with a fan heater in greenhouse. I have a thermostat dial 

but it is just numbers  I cannot find a fan heater that shows actual temperature on the dial .i did buy a small one that does but the lowest setting is 15 degrees any suggestions

    Maybe i've misinterpreted something, but if you have a temperature-triggered (thermostat) plug, can't you just set the temperature on that?

    I would use a max/min thermometer in conjunction with the thermostatic plug ... A little experimentation will soon find the optimum position on the dial.
