Sanyo HVAC CZ-RTC4 Timer Remote Controller

The Sanyo CZ-RTC4 Timer Remote Controller is a wired remote control built exclusively for Sanyo's ECOi and PACi air conditioner and heat pump models. It allows users to remotely adjust their HVAC unit's temperature, fan speed, and operating mode. One of its most notable features is the built-in 7-day timer, which allows users to set the unit to turn on or off at specified times during the day and week. This can increase comfort and energy efficiency by ensuring that the HVAC system is only used when necessary. Furthermore, the CZ-RTC4 includes "Econavi" features and capabilities, which are most likely functionalities designed to optimise energy use depending on occupancy and usage patterns.
