2. Field supplied relay.

3. Interconnection to the Versatronik 300 control onto the INT input. Only dry contact status input to the control.

4. Combustion/Exhaust air blower/damper demand signal based on when the control requests the first boiler to fire.

6. Field supplied relay to provide dry contact to BMS or other device for demand.

!

Notice

The Versatronik 300 control may provide a demand to the boiler system for operation, resulting in the operation of the exhaust/damper device without boilers actually operating. If the boiler temperature is above its actual operational set point, the boiler may not fire, even though a call for heat from the

Versatronik 300 is present.

5

Sequence of Operation

1. Versatronik 300 senses drop in common supply temperature below the setpoint, provides set point demand to first boiler and AUX output turns ON.

2. The AUX output triggers demand for combustion/exhaust air operation.

3. Versatronik 300 waits for input signal from

BMS or combustion/exhaust system before allowing boilers to receive heat demand.

4. If the combustion air input signal is not sensed in 60 minutes, the control will provide a fault output. This time delay value can be altered from factory value.

!

CAUTION

It is possible for the boilers to be demanded ON with the override function and not provide demand signal to the combustion air system in Vitodens systems.

Connection Overview

The Versatronik has three 120VAC outputs for its various functions:

1. The common supply pump is connected to the control at the output marked PUMP.

This is a 120VAC output rated at 5FLA. If a larger amperage pump is necessary to be controlled a field supplied motor started should be used, which can be controlled by the pump output.

2. A field supplied 120VAC relay can be trigged from the AUX output for one of two functions:

External demand of alternate heating sources based on the time/temperature operation of the AUX connection.

Alternate function of combustion air demand to external system. Output active when demand present to the boiler plant.

This is a 120VAC, 3FLA output.

3. The fault output connection can be connected to various 120VAC loads at a

3FLA maximum. A relay can also be used to control an alternate load.

24

Input-120VAC

Input connections for 120VAC

Connection Overview

The Versatronik 300 control come complete with a power cord. Once all of the low voltage and output connections are complete, the unit can be plugged into a standard 120VAC wall outlet.

The power supply outlet should not be switch or controlled by a low water cut off.

The control is rated for 120VAC, 10A.

Depending on the load of the pump, it may be necessary to have a dedicated 120VAC source.

Operational Overview

Logical Operational Output Information

Pump Output

System pump runs if outdoor temperature is below WWSD (minimum run time). Should the control not be programmed for outdoor reset operation, when the common supply set point is greater than 0C/32F, the common supply pump will operate.

The pump output has a factory set delay time of

10 minutes when there is no set point being calculated. If it is necessary to have the supply pump run continuously, it is possible to program so that it does not shut down.

Boiler Cascading

An additional boiler will be called if any of the following are true:

The common supply/LLH temperature is more than 5C (adjustable) below the setpoint

The average modulation for all active boilers exceeds the maximum average modulation

(adjustable)

A boiler will be taken off line if any of the following are true:

The common supply/LLH temperature is more than 5 (this setting is adjustable) above the setpoint.

The average modulation for all active boilers drops below the minimum average modulation

(this setting is adjustable)

Boilers will be brought on/off-line no faster than one boiler every 2 minutes under normal circumstances.

Boilers will be brought on in the following sequence:

All boilers not listed below

Eco-lock

Boilers reporting a fault

Boilers to which do not appear to be

communicating

If all non-Eco lock boilers are online or faulted

AND the set point can’t be met, turn on the AUX output.

AUX Output-Heat Demand

If all boilers are online (or faulted) and setpoint can’t be met; turn on AUX Output. The AUX

Output is function of not being able to be within the set differential for a set period time. Once the

AUX Output is energized, it will be on for the set minimum amount of time until the set differential temperature is achieved.

AUX will switch on when all non-faulted, non-eco lock boilers are running and the common supply temperature drops below the setpoint. It must drop to or below the differential specified in the setup menu. It must have been below this temperature for at least the amount of time specified in the configuration menu

Once running, it will run until the minimum amount of time specified in the setup menu has elapsed and either of the following conditions are met:

The common supply temperature is satisfied

Either of the non-faulted, non-eco lock boilers stages off

AUX Output-Combustion Air Function

The AUX output can be alternately programmed for a combustion air device function. When there is a call for heat, the AUX Output will turn on. This output can be used to demand some device such as a damper or blower rated for 120VAC.

A proving signal is then sensed by the INT input as a confirmation that the combustion air system is functional and then will allow the boiler plant to continue operation. This signal can only be in the form of a dry contact.

As part of the combustion air function, there is an

AUX Wait timer function that if the proving signal has not been sensed by the control in 60 minutes

(adjustable) an alarm will be triggered.

Operational Overview

Logical Operational Output Information Continued

INT Input

When the interlock mode is enabled through the set up menu and the INT contact is closed, the boiler plant will be allowed to operate. Should the

INT contact open for whatever reason, the boiler plant will shut down via communications and a C1 failure code will be present in the display of the control. As soon as the contact is again closed, the fault will clear and the boiler plant will again to stage on the boilers.

An alarm function is also possible which is set in coding. Should the control sense that the INT is open, the Fault output will turn on. As soon as the

INT input is sensed, the fault will clear automatically.

Boiler Rotation

Boilers will rotate on the hours programmed into the control. Rotation will take place on the set accumulated time when the common supply set point is satisfied.

Stage ON (5C/41F to 30C/86F)

Maximum boiler modulation setting allows the cascade control to only bring on another boiler should a currently running boiler exceeds this value. This is dependent on system operating temperatures

The Stage ON function is based on when another boiler is forced ON if the current boiler load is not sufficiently satisfying the common supply temperature. Should the common supply actual temperature drop below the set point plus this value, a boiler will be brought on.

Stage Down (5C/41F to 30C/86F) As the common supply set point is satisfied by this amount, boilers will start to be staged off in conjunction with a 2 minute delay

Always run lead boiler pump

Boiler minimum modulation setting has a factory value of 30%. This value is the factory default.

All Boilers (Yes/No)

By default, the lead boiler pump will always operate. By selecting the alternate function, the lead boiler pump will turn off if there is no boiler call for heat.

This setting allows the control to bring on all boilers, including ECO Lock boilers to achieve the common supply set point.

Boiler 1 LON Address

The rotation hours from when the boilers rotate lead boiler is set here. The boilers will rotate as long as the common supply/LLH set point is satisfied

A boiler staging delay can be adjusted here to provide sufficient time before bringing on another boiler. This allows the boilers to be able to satisfy the current load requirements.

It is possible to select a “lead” group of boilers which are all of the boilers which are to function before the “lag” boilers. The boilers in both the lead and lag will rotate. The lag boiler group should never operate before the lead group.

It is possible to put a boiler into ECO lock mode which is a function of the current outdoor temperature. As the outdoor temperature drops below the ECO Lock setting, the boiler will be allowed to be part of the cascade function of the Versatronik 300 control.

Overview Description

The boiler cascading operation of the Versatronik

300 control is based on time/temperature/ modulation functions. The digital communications between the boiler controls and the 300 provide information regarding the current percentage of burner modulation. The 300 control uses the burner modulation to be able to bring on another boiler should the % setting be exceeded. Because of this logic, it is possible to have a larger number of boilers on at a lower firing rate. The opposite of this is also true. By programming a higher % value, it is also possible to have the boilers function at a greater modulation level.

Burner modulation is a function of the boilers and not controlled by the Versatronik 300 control. As the individual boiler temperature set point is being satisfied, the boilers themselves will modulate down.

Cascading Sample Graph

The above picture shows a typical cascading ON and OFF of boilers to achieve the set point demand from either outdoor reset, heat demand or 0-10VDC input.

As the actual common supply or LLH temperature drops below the set point, a call for heat will be provided to the lead boiler. This call for heat takes place approximately 2C below the set point. The set point, which can be seen on the screen of the

Versatronik 300 control, is provided to the boiler.

The boiler control will process this signal and based on the current boiler water temperature, will decided to fire the burner or not. Since the pump will be on and the actual boiler water temperature will decrease, the burner will fire.

Burner modulation will take place as a function of the internal PID operations of the control. The enabling of another boiler is a function of the

Maximum Boiler Modulation % setting and the

Stage On setting, which is a temperature setting.

If the Maximum Boiler Modulation % is exceeded, the next boiler will be provided the set point and again it is responsible for its own modulation to achieve boiler set point.

The operation of the boilers and the modulation is a function of the flows through the boiler and internal PID functions. Should the common supply temperature drop because of extra loading, the

Stage On setting may be exceeded which will force another boiler on as a way to ensure that the common supply set point is achieved.

As the common supply starts coming up in temperature as a result of the boiler operation and modulation, the boilers themselves will start to modulate down. Based on the number of currently running boilers and the Minimum Boiler Modulation setting, the boilers may start to be staged off. As well, it is possible that the

LLH/Common Supply

Temperature boilers themselves have modulated down and turned off but still have a call for heat in the form of a boiler temperature set point.

Depending on the current operation of the system, the Versatronik 300 control looks at the Minimum

Burner Modulation of the active boilers. Should the average modulation of the currently active boilers be equal to or less than this setting, a boiler will be staged off in conjunction with a 2 minute delay.

Cascade Adjustment Strategies

Pure Modulation Staging

Cascade operation as a function of burner/boiler loading, increase the Stage On value so as to not force boilers on earlier as a function of temperature. This may be upwards to a value of

10C/18F or 15C/27F. Adjust the Maximum Burner

Modulation setting to a value where the next boiler should be brought on. Each successive boiler will come on at the Max Modulation value.

To have the boilers stage off earlier, set the

Minimum Burner Modulation to a value higher than the default value of 30%.

Temperature Dependant

By either leaving the Stage On value at its factory default setting or lowering it to a smaller value, successive boilers will be brought on quicker. Each boiler will modulate again to achieve the boiler temperature set point.

Additional Alarm/Fault Information

The Versatronik 300 show fault codes in hexadecimal format to conserve screen space on the user interface.

In which base-format this fault can be displayed depends on your BMS software.

This example shows how to display this fault code in hexadecimal, and Text format in

Niagara AX.

To display in hex, you can use the KitControl -

> Util “Numeric Bit And” object’s mask input.

To display the equivalent fault text value, you can use the KitControl -> Conversion

“Numeric To Enum” object and type out the enum range for all Viessmann error codes.

These values can now be displayed on a px webpage by pointing a Bound Label to the appropriate slot values.
