Not maintaining the set temperature is not always a fault of the T-stat. I'm not sure about what you're saying because there could be a problem with the other parts of your unit. Remember, the T-stat is only a switch, but look at any of these anyway

There is a Span setting on the thermostat causing that, most newer thermostats have a adjustable span from 1 to 5 degrees, if your thermostat has a option menu, scroll through the options and see if you find a option called Span if its at 3 or 4, change it to 1 or 2, then your furnace will cycle on sooner. If you have your owner manual still for it that should show you how to do it.

The furnace may not be getting power. It could have been turned off when switched over from heating to cooling.

I wonder if they shorted a wire a during install. That is where I would begin.

More than likely, this is what you have:

Red- Power- (RC/RH)
White- Heat- (W)
Green- Fan- (G)
Blue- Cool- (Y)

Usually, the only times you need more than 4 wires are:

1. You have a HeatPump system.
2. Your new digital thermostat does not use batteries, which then you have to have a common wire to power the thermostat.
