temperature reaches 100C. It will be turned on again when temperature drops

below 97 °C. For the cooling mode, the compressor will be turned off when T=SV.

It will be on again when T>SV+Hy.

• CooL. When Cool=0, the controller is set for heating control (reverse action).

When Cool=1, the controller is set for cooling control (direct action).

• Out, Output power reduction.

function will allow you to control the maximum output power delivered by the

heater. For example, if you set Out=50 and your heater is 1000 watts, the output

will use 50% of the 1000 watts as the full output. It thinks the 1000W heater as a

500W heater. When the PID algorithm determines 50% output value, the actual

power output will be 250 watts. This function can be used in two situations.

1) When you have a very powerful heater and using a very small pot of water to

cook at very low temperature, for example, a 1400 watts heater with a one litter (1

qt) pot of water at 130 °F. The heater is too powerful for the small water volume.

The moment it is on, it releases too much energy to cause the temperature to

overshoot. Although it is still possible to stabilize the temperature with proper PID

parameters, it is much easier to control if you limit the maximum output to 25%.

Ideally, an optimized temperature control system should consume about 25 % of

the heater power at set temperature (steady state), for example, if you found out

that only 50 watts of energy is needed to maintain the temperature at 60 °C

(141°F), ideally you should use only 200 watts heater for the job. Too much power

will make the system over react too quickly. Too little power will make the system

too slow in response. By using the OUt function, you can make the 1400 watts

heater to act as a 200 watt heater for stable temperature control.

2) When the cooker consumes more power than controller can handle, for

example, if you have a 12A, 120V AC heater and your cooker contains more than

38 liter (10 gallon) of water. It might take more than 90 minutes of full power

heating for controller to heat up the pot. Long time of full power operation might

cause the controller to over heat. You can set the output to 80%. It will prevent the

controller from over heat by staying a full power too long. For details, please see

Appendix 1.

• C-F, Display unit setting. You can set the display either Celsius or Fahrenheit.

• TK, Timer. When TK is set to 1, the timer is on. If you want the controller stays on

without turning of by itself.

This group of parameters is accessed by input code 155. Figure 5 is the flow chart that

shows how they can be changed.

It is expressed as a percentage value. This
