Controls Questions, Straight Answers
Why does the thermostat say 'aux heat' all the time in winter?
Either it's genuinely too cold for the heat pump (undersized or losing capacity), the balance point/lockout is set wrong, or the stat's staging is misconfigured. Aux running constantly turns a heat pump's economics upside down — set intelligent lockout and check the defrost cycle before blaming the equipment.
Smart thermostat keeps rebooting or dropping Wi-Fi — why?
Nine times out of ten it's power: no C-wire and the stat is power-stealing from a board that hates it. Land a real common wire or use the add-a-wire module. The tenth time it's rural Wi-Fi that drops nightly — some houses just want a quality conventional stat.
