TLDR Review: KING K101-C Thermostat
Pros
- •Designed specifically for cooling applications and performs well in that role.
- •Reliable and consistent operation for cooling control.
- •Well made with a solid dial mechanism and easo-read numbers on the display.
- •Effective for controlling exhaust fans and maintaining temperature in hot or greenhouse environments.
- •Simple to set up and use, meeting expected needs effectively.
- •Fairly accurate in maintaining set times and activating fans automatically once the desired temperature is reached.
Cons
- •Not suitable for heating purposes; the heat function is unreliable and only triggers at very low temperature settings.
- •Temperature readings can be off by about 10 degrees Fahrenheit, requiring user adjustment for accuracy.
- •Has a large temperature differential (around 19 degrees), which can cause excessive A/C run times before shutting off.
- •The thermostat may only shut off A/C when set to an unusually high temperature like 90 degrees, limiting precision control.
- •Customer support responsiveness has been reportedly poor.
Bottom Line
If you’re looking for a basic, rugged thermostat primarily for cooling applications like exhaust fans or greenhouse environments, the KING K101-C delivers on reliability and simplicity. However, don’t expect precise temperature control or heating functionality out of this thermostat—it’s really built with cooling in mind and has some accuracy and differential quirks that might require tinkering. If you need more precise or dual-functionality thermostats, you may want to explore other options better suited to those demands.
