User Manual

1. Overview
BTC201 is an easy-to-use, safe and reliable dual relay output temperature controller. It can be used as Over-
temperature protection and automatic temperature control system for various electric appliances such as
equipment for home-brew, aquarium, pet breeding, incubation, BBQ, seedling heat mats, oven
temperature control, terrestrial heat control, constant temperature cycle of heating pump, culture
fermentation, accelerating germination, electric radiator, electric oven, etc. The Plug and Play design with
dual relays enables it to connect refrigeration and heating equipment easily to realize ideal temperature
control. There’s option for Centigrade or Fahrenheit readout. With large output power 1650W (at 110V) /
3300W (at 220V), it’s suitable for most applications. BTC211 is designed with compressor delay protection
for refrigeration, high / low temperature alarm, and sensor failure warning, which makes the temperature
controller more safe and reliable. Functions such as temperature calibration, separate setting of differential
for refrigeration and heating, enable more accurate temperature control.
