New construction, new installation. Bryant 215B heat pump.
Two problems:
1) When it's stupid cold, heat pumps run for their defrost interval and then go into defrost mode. During defrost, the electric backup kicks in. Rather than trying to keep track, I'd like to add an outdoor thermostat to shortcut the process.
2) When the unit kicks on (summer or winter), all the lights in the house dim. It's just annoying. My battery backup for IT stuff doesn't trip a low voltage alarm, but I'd like to eliminate this if possible. I know these units have a large capacitor to compensate for the startup draw. Is it possible to install a larger capacitor or something else that can be done here?
