Understanding R & RC on a Thermostat

By

The thermostat is a crucial component of your HVAC system, responsible for maintaining the desired temperature in your space. Two often-confused terms in this context are 'R' and 'RC' - we'll demystify these labels to help you understand your thermostat better. Let's dive in.

First, it's essential to understand that 'R' and 'RC' are not universal designations; rather, they pertain to specific thermostat models or brands. Let's break down these terms in the context of popular Honeywell and GENERAL ELECTRIC thermostats.

Understanding 'R' in Honeywell Thermostats

In Honeywell thermostats, the 'R' usually signifies the first digit in the model number and corresponds to the heat source or the system type. For instance, an 'R8181' is a non-programmable, outdoor reset thermostat, while an 'RTH6500D' is a touchscreen, 7-day programmable unit.

Knowing the 'R' series can help you choose the right thermostat for your heating system. Honeywell offers 'R' series thermostats for gas, oil, and electric heating systems, as well as heat pump systems. However, always check compatibility with your existing setup before purchasing.

Honeywell 'R' Thermostats with Humidity Control

Notably, some Honeywell 'R' series thermostats, like the 'RTH8500' or 'RTH9580', include built-in humidity control. These units can both monitor and control the humidity levels in your home, providing added comfort during summers and protecting your belongings from excessive dryness in winters.

Numerous 'R' series thermostats come with Wi-Fi connectivity, allowing remote access and control via smart devices like smartphones or tablets. This feature enables scheduling, temperature adjustments, and even alerts for unusual system activity, all from your mobile device.

A popular choice is the 'RTH6500D', which allows 7-day scheduling, intuitive touch screen controls, and user-friendly programming. Additionally, it is compatible with Honeywell's Total Connect Comfort app for remote control and monitoring.

GE Thermostats and the 'RC' Designation

General Electric (GE) thermostats use the 'RC' designation with their wall thermostats, prefixed with the model number. For example, the 'JAN085000027' is a GE wall thermostat, with 'RC' signifying the control type - in this case, a gas/electric unit with Zone Valve Control.

GE thermostats with the 'RC' designation generally feature a universal design suitable for both natural gas and electric heating systems. However, ensure compatibility with your existing system before installation.

GE Thermostats with 'RC' - Control Systems

GE's 'RC' thermostats often include advanced control systems for multiple heating zones. For instance, the 'RC-8500' provides independent control for up to four different zones, allowing optimal comfort and energy efficiency across your home.
