Extreme temp set by tenant

[Ron Mussatto]

I have read here the multiple posts from the landlord concerned about tenant setting thermostat to the extreme causing excessive HVAC wear and tear.  But I have not seen a post about the consequences to tenant's health and unit from extreme AC temp.

I have tenants who set the thermostat to 62/63 when it is 95 plus degrees outside.  This causes moisture in walls, even cabinets feel moist (cabinets have warped).  Research shows this can lead to mold issues. This is beyond a wear and tear or AC unit and now the health of a tenant.  

Without draconian sounding measures, has anybody successfully inserted language in the lease to regarding setting temp to extremes?
