KT8230 °F/℃ Temperature Controller

The temperature range can reach 572℉/300℃ . Output 30A relay.Control temperature by setting mode, temperature set value and difference value.Support delay start and temperature calibration.Alarm when temp exceed temperature limit or sensor error.All parameters setting can be saved after restart. Heating, Cooling mode

Cooling mode: Measured temperature ≥ setting temperature + differentialHeating Mode: Measured temperature ≤ setting temperature – differential

Can be used for domestic freezer, refrigerator,industrial chiller, steamer, industrial equipment and other temperature control applications.

Freezer

Greenhouse/Breeding

Incubator

Error Code

EE1

Sensor fault.

Check if the sensor is broken or poor contact.

HH1

High temp. alarm .

Measured temperature exceed limit

LL1

Low temp. alarm .

Measured temperature exceed limit

2 Wire Connection

Note

Q: Why there is no output voltage？

A: This is a relay temperature controller, There is no voltage output directly, you need to connect additional power supply for the load, then it can turn on/off the load.

Q: There is a way to calibrate when temperature gives error?

A: Yes, In normal working status, press SET for 3 seconds to enter into setting parameter mode. When display HC, press UP or DOWN button to switch codes to CA ( -30.0°F～30.0°F/-7℃~7℃ )

Q: Why it does not turn off the light as setting ?

A: Please check if you set the value for PL, if PL≠0, the display will flash, the cooler or heater only start to work after the time of PL.

Q: Why it only can be set in limited range, not as description -22~572℉/-30~300℃

A: HS and LS can set the high and low limit of setting temperature: For example: if HS = +60, LS = -10, the setting temperature only can be

set between -10~+60. so if you want to set a value beyond this range, please change HS and LS at first.

【Wide temperature range.】The range for KT8230 is -22~572℉/-30~300℃,This is a relay temperature controller, There is no voltage output directly, you need to connect additional power supply for the load, then it can be set by differential (1~80℃/1~120℉) to turn on/off the load, it is like a switch.
【Output is 30A relay, more accurate.】The temperature controller 120V can be used for big power equipment, like incubator, brooder, refrigerator,Fermenter,Greenhouse,etc. 1°F accuracy to keep the temperature in desired range.
【Support delay start function and temperature correction.】The cooler and heater will delay to work if you set the delay time(PL: 0~7min) not 0, You can set depend on what you need. -30.0°F～30.0°F/ -7℃~7℃ calibrate the temperature when there is error.
【Safe protection.】Temperature Regulator will alarm when it exceed temperature limit or sensor error, alert you when something wrong happened. You can also set the low(LS) and high temperature limit(HS) to change the temperature range, LS < Setting Temperature < HS.
【Simple operation.】 All parameters setting can be saved after restart, you don’t need to set the thermostat regulator when power off, or restart it from vacation. 2m NTC sensor allows more possibility for home
