how do you set up a back up thermostat?
the other day my herpstat when blank. not sure why but nothing was on the screen. i ran through the set up menus and everything was normal. after the set up menu, it just started flashing random numbers and squares. so i reset it and it has worked fine now.
i did notice that i never hear the fan running so ive been checking internal temps of the unit. they are running around 92. is this high or normal and what temp is the fan supposed to kick on at? there is no setting to change the temp at which the fan should turn on but it can be run constant. i have been doing this when i come in the room to check on everyone.
