I. Description

The ST–88zPID temperature regulator is intended for use with central heating boilers.

The regulator is used for controlling the central heating water circulation pump, hot

consumption water pump and blow (fan).

The EU-88zPID is a PID-basedcontroller using a continuous signal. In this type

of controllers, the fan power is calculated based on boiler temperature and flue gas

temperature measured at the boiler outlet. The fan runs continuously and its power

depends directly on the measured boiler temperature and flue gas temperature as well

as the difference between the two parameters and their setpoint values. Advantages of

zPID regulators include their ability to maintain a stable setpoint temperature without

unnecessary overregulations and oscillations.

By fitting the controller with a flue gas outlet sensor, you can save from a few

up to several percent of fuel, and ensure a steady water temperature for a longer service

life of your heat exchanger (boiler). Flue gas outlet temperature monitoring ensures

reduced harmful dust and gas emissions. The thermal energy from the flue gases is

used for heating instead of being wasted and disposed of through the funnel.

Research results presented below were obtained using the Tech PID-based

controller:

and the controller without PID control:

You can change all parameters with an encoder knob. Turning the knob allows you

to select a function or modify its value, while pressing the knob allows you to enter the

function or confirm changed values. To leave any function, turn the knob until you reach

the <<EXIT position and confirm your selection by pressing the knob.

I.a) Basic Terms

Fire up. The cycle begins when you activate the fire up function in the controller's menu

and is active until the central heating boiler temperature reaches 40oC (the default fire-

up threshold), on condition that the temperature does not drop below this value for 2

minutes (the default fire-up time). If these conditions are met, the regulator will switch

to the duty mode and the manual operation symbol on the housing will be deactivated.

If the controller fails to reach parameters required for entering into the duty mode

within 30 minutes from activation of the fire-up function, the "Unable to fire up"

message will appear on the display. In such a case, the fire-up cycle needs to be

restarted.

Duty –once the fire-up cycle is finished, the controller enters the duty cycle. The duty

cycle is the basic functionality of the regulator. The blow is controlled automatically

using the zPID algorithm and the temperature is close to its setpoint value. In the user

menu, fan item will appear in place of the fire-up function. The fan can be deactivated

when needed (e.g. while feeding fuel). If the temperature rises unexpectedly by more

than 5oC over the setpoint value, the so-called Supervision Mode is activated.

Supervision Mode –the mode is activated during the Duty Cycle if the temperature

rises by more than 5oC over the setpoint value. In such case, the controller is switched

from the PID control to manual settings (according to parameters entered in the Fitter’s

Menu) to reduce the temperature of the circulation water.

Damping –if boiler temperature drops by 2oC below the fire-up threshold and fails to

rise above this value for 30 minutes (default damping time), the regulator will switch

to thedamping mode. While in this mode, the fan is deactivated and the display shows

"Damping".

In case of voltage loss, the regulator ceases to operate. When power is restored, the

controller returns to operation with previously set parameters using its built-in memory.

Lack of voltage does not cause the stored parameters to be lost.

II. Regulator Functionality

This chapter describes regulator functionality, how to change settings and navigate in

the menu with the encoder (knob). Depending on the mode the boiler is currently in,

the display will show boiler operational parameters. The given mode is selected by the

user.

.1. Main Page

During normal operation, the LCD display shows the Main Page containing the following:

●Boiler temperature (to the left of the display).

●Setpoint temperature (to the right of the display).

●Fan stop. After manually stopping the fan while in the duty mode, the star symbol

(*) will appear in the top right corner.

●Operation Mode. In the bottom right corner, the corresponding letter of the

operation mode is displayed. Depending on the operation mode, the corresponding

42 Oc | 55 Oc

C.H. Setpoint D

symbol is displayed:

D –house heating, B –water heater priority,

R –parallel pumps, L –summer mode.

Pressing the encoder will move you to the main menu. The display shows two

options of the menu. To select a different option, turn the encoder knob.

.2. Changing the central heating and hot consumption

water setpoint temperature.

In order to change the setpoint temperature of the central heating (while in "C.H.

screen" main view), turn the encoder knob and (after setting a desired value) press it

to confirm the change.

In order to change the setpoint temperature of the hot consumption water (while

in "H.C.W. screen" main view), turn the encoder knob and (after setting a desired value)

press it to confirm the change.

Chapter "Screen" describes methods of changing the main screen view.

.3. Firing up

This function allows you to easily fire up the boiler. After igniting the boiler, you

need to activate an automatic fire-up cycle. By selecting optimum parameters, the

boiler uses the zPID function to smoothly switch to the duty mode. If the boiler reaches

the fire-up threshold temperature, the fan item will appear instead of the fire-up

function. From now on, the option will be used to activate/deactivate the fan. This

setting allows you to temporarily deactivate the fan at any time, e.g. while feeding fuel.

If during the fire-up cycle the boiler does not reach 40OCwithin 30 minutes, (default

parameters), the following warning message will appear on the display:

To restore the boiler to operation, switch off the alarm by pressing the

encoder and restarting the fire-up procedure.

.4. Manual Mode

For your convenience, the regulator features a manual mode module. In this mode,

each individual actuator is enabled and disabled independently of the other. In addition

to the Manual Mode function, the Blow Force function has been provided.

.5. Fuel Type

This option allows you to select one of three fuel types (coal, fines and wood) for use

in the boiler. Each fuel type has a fan operation mode assigned to ensure the right

burning process.

.6. Central Heating Pump Activation

With this function, you can set the temperature that will activate the central heating

pump (the temperature is measured on the boiler). The pump will start if the setpoint

temperature is exceeded. The pump will be deactivated when the boiler temperature

drops below the activation temperature (minus hysteresis, e.g. 2OC). In this case, the

pump will stop at boiler temperature of 33OC.

.7. H.C.W. Pump Activation

With this function, you can set the temperature that will activate the hot consumption

water pump (the temperature is measured on the boiler). Above the setpoint

temperature (e.g. 40OC), the pump is activated and operates depending on the selected

operation mode. The pump will be deactivated when the boiler temperature drops below

the activation temperature (minus hysteresis, e.g. 3OC). In this case, the pump will

stop at boiler temperature of 37OC.

.8. Operation Mode

With this function, you can select one out of four operation modes.

.8.a) House Heating

If you select this option, the regulator will switch to the house heating mode. The central

heating pump starts to run above the pump activation temperature (set to 35OC by

default). Below this temperature (minus central heating hysteresis), the pump is shut

off. While in the house heating mode, the letter D is displayed in the bottom right corner

of the main screen.

.8.b) H.C.W. Priority

Activating the hot consumption water priority will cause the regulator to switch into the

water heater priority mode. In this mode, the (hot consumption water) heater pump is

activated until the set H.C.W. temperature is reached. Then, the H.C.W. pump is shut

off and the C.H. pump is activated. The central heating pump will run until the water

heater temperature drops below the setpoint value (and the H.C.W. hysteresis); then,

the C.H. pump is shut off and the H.C.W. pump is activated.

In this mode, the fan is operated as long as the temperature is below 62°C to prevent

the boiler from overheating.

The hot consumption water priority function consists in that the consumption water is
