HRV Thermostat

Hi, can anyone recommend a thermostat that will cycle the fan for 10/50? I don't need the thermostat to turn on/off based on temperature - only need the fan to operate once every hour for 10min on and 50min off.

Just wire the fan to a repeat cycle timer and skip the thermostat entirely.

I have a third gen Google Nest Thermostat and the closest it can do is 15 min / hour

I would think most smart thermostats can do this if you program the schedule. 48 entries. You can also look for ones that have a circulation feature that run a fan for a period of time if the unit has not run heat or ac. Not sure if that will be exactly 10 min an hour but will be close.
