3. Boost mode settings (access code 122)

A boost mode is an operating mode on RDK-300B that allows the user to

quickly cycle between two set temperatures, a lower standby temperature and

a higher boost temperature, by simply pressing down the control knob. There is

no need to turn the knob back and forth to adjust for the desired set

temperature. A boost mode also allows the user to set up a boost timer which

automatically lowers the set temperature from boost to standby after a period

of time.

Three (3) boost modes are available, which are named as "b-1", "b-2", and

"b-3". There are three parameter settings for each boost mode: standby

temperature (x-S), boost temperature (x-B), and boost timer (x-T), where "x"

represents the boost mode number. A user can adjust and save customized

settings for each mode in the menu of 122.

Details about each boost mode setting

x-S. Standby temperature. It is a relatively low set temperature at which the

user feels comfortable to leave the coil heater for a long time when the heating

system is not in use. The standby temperature must be lower than the boost

temperature.

x-B. Boost temperature. It is a high set temperature at which the user is going

to use the coil heater. The boost temperature must be higher than the standby

temperature.

x-T. Boost timer. It is a timer for boost temperature. Once the timer is reached,

the controller will automatically switch set temperature back to the standby

temperature. A user can also deactivate the boost timer by setting it to "OFF",

which means the set temperature will remain at the boost temperature till the

user press down the control knob.

4. Temperature control parameters (access code 166)

Press down

knob

This group of parameters is for adjusting the temperature control performance.

Table 1 shows the list of parameters, their range and the initial factory settings.

For most heating coils and nails on the market, the P, I, and d do not need to

be changed. Please do NOT change them unless you are very familiar with

manually tuning PID controllers. In most cases where the control result is not

ideal, adjusting the "oth" should be able to solve the problem.

Details about each parameter

 P. Proportional band. The unit is in degrees. This parameter controls the

output of the controller based on the difference between the measured and

set temperature. The larger the P value, the weaker the action (smaller gain).

For example, if P = 7, the proportional band is 7 degree. When the sensor

temperature is 7 degrees below the set point, it is out of the proportional

band, and the controller will have 100% output. When the temperature is 5

Initial

degree below the set point, the output is 71%. When the temperature is

300°F

equal to the set point, the controller will have 0% output (assuming integral

550°F

and derivative functions are turned off). This constant also affects both

OFF

integral and derivative action. Smaller P values will make the both integral

300°F

and derivative action stronger.

550°F

OFF

 I. Integral time. The unit is in seconds. This parameter controls the output of

300°F

controller based on the difference between the measured temperature and

the set temperature integrated with time. The integral action is used to

550°F

eliminate temperature offset. Larger number means slower action. For

OFF

example, when the difference between the measured and the set

temperature is 2 degrees and remains unchanged, the output will increase

continuously over time due to the contribution of the integral term until it

reaches 100%. If the temperature fluctuates up and down constantly

(system oscillating), increase the integral time I. If the controller is taking too

long to eliminate the temperature offset, decrease the I. Usually this

parameter does not need to be changed.

 d. Derivative time. The unit is in seconds. The derivative term contributes to

the output power based on the rate of temperature change. Derivative action

can be used to minimize the temperature overshoot by responding to the

rate of temperature change. The larger the d value, the faster the reaction.
