What Buyers Ask Before Inquiry
KTO111 is Normally Closed. It switches ON the heater when temperature drops below setpoint for heating and antiu2011condensation. KTS111 is Normally Open, it turns on cooling fans when temperature rises too high for heat dissipation. They are used for two opposite thermal control purposes.
It is mainly developed to cooperate with cabinet heaters and fan heaters. Our intelligent dehumidifiers adopt builtu2011in digital humidity control with 485 communication, which works independently. We do not recommend connecting KTO111 to dehumidifiers.
No. It is a pure mechanical thermostat with a manual rotary dial only, no digital screen. If you need digital display and precise programmable control, you can choose our electronic digital temperature & humidity controllers.
