Mechanical Design and installation

The unit consists of two parts: (a) The power case with attached mounting plate and (b) the front part.

Mounting location

• On an easy accessible interior wall, approx. 1.5 m (4.5’) above the floor in an area of average temperature.

• Avoid exposure to direct sunlight or other heat sources, e.g. the area above radiators and heat emitting electrical

equipment.

• Avoid locations behind doors, outside walls and below or above air discharge grills and diffusers.

• Location of mounting is less critical if external temperature sensors are used

Installation

1. Connect the wires to be connected to the terminals of the power case according to wiring diagram

2. Install the mounting plate to the flush mounting box. Make sure that the nipple with the front holding screw is

facing to the ground. Make sure the mounting screw heads do not stand out more than 5 mm (0.2”) off the surface of the mounting plate.

3. Ensure that the jumpers are set correctly.

4. Slide the two latches located on the top of the front part into the hooks at the upper side of the mounting plate.

5. Carefully lower the front part until the interconnector reaches the mounting-plate. Continue pressing in a gentle

way until the front part is fully connected. While inserting the connectors, a slight resistance can be felt. This is normal. Do not use excessive force!

6. With a Philips-type screw driver of size #2, carefully tighten the front holding screw to secure the front part to

the mounting plate. This screw is located on the front lower side of the unit. There is no need to tighten the screw too much.

Standard display

Standard display is enabled with parameter UP08. This display mode is active if no UP/DOWN or OPTION key has been pressed during the previous 30 seconds. The contents of the large and small digits may be chosen with parameters UP09 to UP10. Should Standard display be disabled, the selected loop setpoint will be displayed in the small digits, the associated input in the large digits and the output in the right hand scale.

Changing of set points

If two control loops are enabled, step through loop 1 and loop 2 by pressing the OPTION/RIGHT button. The large digits show Lp1 and Lp2 alternately with the set point of that loop shown in small digits. With the desired control loop displayed change its set point with the UP/DOWN buttons. If only one control loop is enabled press the OPTION/RIGHT button to display set point in small digits and adjust with UP/DOWN buttons (Lp1 or Lp2 is not shown). Changing of setpoints may be disabled with UP01.

Override of secondary set point in cascade control

If cascade control is active (for example VAV control), it is possible to override the primary loop and manually set the set point of the secondary loop. While the secondary loop is displayed change the set point with UP/DOWN keys. The manual indication will show on the display. (For VAV this would mean the loop is now changed to CAV. This is especially useful while tuning the VAV system) Pressing the OPTION key to move back to the temperature loop will cancel manual override. Manual override may be disabled with UP02.

Control Functions

Lp1: Temperature control loop: Signal input: either internal or external passive temperature probe

Lp2: Universal control loop: Signal input: analog input or internal humidity sensor (-H version only) Each control loop may utilize 6 binary and 2 PID control sequence functions. Control sequences will be activated once

assigned to a physical or logical output.

Manipulation of the set point

Standby set point shift X

point W

is reduced and the cooling set point WC increased by the value of the standby set point shift X

Dead Zone Span X

: The dead zone span lies between the heating and the cooling set point.

Minimum and Maximum Set Point Limits: Limits the adjustable range of the loop set point. The limits for heating and

cooling sequence may be chosen individually.

Cascade Control: The output of the primary control loop determines the set point of the secondary control loop. It is possible to choose only the direct or reverse sequence or both of them. The output of the set point providing control loop is spanned between the minimum and maximum set point limits. The set point limits for heating and cooling sequence are defined individually.

Summer – Winter Compensation: Shift the set point either towards the set point minimum (negative shift) or the set point maximum (positive shift) depending on an external input signal. This is done to compensate the set point due to a change in the environment. It is most commonly applied to outside temperature. Summer-Winter compensation is activated through parameter 1L07 or 2L07.

IP22 selects the compensation input signal, either external temperature or analog input.

The winter compensation is active when the outside temperature drops below the upper limit of winter compensation IP25. Depending on parameter IP23, the setpoint is now shifted towards the heating setpoint minimum or maximum. The maximal compensation is reached when the temperature reaches the lower limit IP24. The actual set point will in this case be equal to the minimum heating set point limit for a negative shift or the maximum set point limit for a positive shift.

The summer compensation is active when the outside temperature exceeds the lower limit for summer compensation IP27. Depending on parameter IP26, the setpoint is now shifted towards the cooling setpoint minimum or maximum. It reaches its maximum when the temperature equals the upper limit IP28.

Example: Summer – Winter compensation active in loop 1. 1L07 = 3

: This function shifts the set point while the operation mode is standby. The heating set

Integral & Differential Control:

The algorithm used reduces the swinging tendency of the control loop and improves a direct approach of the current value to the setpoint. The ID part is defined by two parameters:

The time interval TI specifies how fast the control sequence reacts. A low value (short interval) increases the swinging tendency and with it the risk of an instable loop. A high value (long interval) slows than reaction time.

The integral gain factor KI specifies how strong the control sequence reacts. Opposite to TI a high gain factor increases instability and a low factor delays the response of the controller.

We recommend the following values:

For air based heating systems: TI = 3s, KI = 1.0

For floor heating systems: TI = 5s, KI = 0.5

For air cooling systems: TI = 3s, KI = 1.2

For humidifying systems: TI = 60s, KI = 0.4

For dehumidifying systems: TI = 70s, KI = 0.3

Pressure Control (VAV): TI = 1s, KI = 0.8 (depending on speed of actuator KI varies)

Binary Control

Each loop has three reverse- (heating) and three direct- (cooling) acting binary sequences. The offset to the setpoint is adjustable for each sequence. The switching hysteresis is adjustable per control loop.

Action of stages: The stages may be activated according three different patterns: One at the time: Only one stage is active at the time. The lower stage will be switched off when the higher stage gets

Cumulative: Multiple stages are active at the same time: The lower stage stays activated when the higher stage

Input Configuration

General

Alarms: Each input features low and high limit alarms. Each alarm is defined with a limit, a hysteresis and an enable

parameter. The limit specifies the input signal level required to trigger the alarm. The hysteresis defines the difference between input signal and limit required to return the alarm state to normal. Once an alarm is triggered it will be displayed as ALA1, ALA2, ALA3 and ALA4. Each alarm needs to be acknowledged by pressing the RIGHT key. ALA1 = Lower limit of the input signal of control loop 1 (temperature) has been reached ALA2 = Upper limit of the input signal of control loop 1 (temperature) has been reached ALA3 = Lower limit of the input signal of control loop 2 (universal) has been reached ALA4 = Upper limit of the input signal of control loop 2 (universal) has been reached

Averaging function: Averaging function is used to prevent unwanted fluctuation of sensor signals. The controller measures every second the signal inputs. The input signal is now built over a number of measured values. Select how many values should be used to calculate the averaging signal. Control speed will slow down when a large number of samples are used for an averaging signal. This should be taken into account when defining the control parameters.

Compensation: Adjust input values if required

mode. The operation mode cannot be overridden by using the terminal or time schedules. Connecting the external temperature input to GND returns control of the operation mode to the terminal and time schedule. This function may be used as window contact to prevent loss of energy. Control heat and cool setting of your controller from a central location by switching a contact to GND. Note: all ground levels of involved controllers must be the same. Choose if heat or cool is to be active when contact is open. The external input may be used to automatically determine heating or cooling mode. Connect a qualified passive sensor to the external input and measure the temperature of the supply media. Heating or cooling mode are activated once the supply temperature is above or below the respective limits. The limits may be defined in software. Standard is 16°C (60°F) for cooling and 28°C (82°F) for heating.

Universal Input:

The analog input signals may be configured with a jumper to 0-10V, 0-5V and 4-20 mA. The jumper is located on the front side of the power part. The drawing on the right indicates the jumper placement for each signal type. The factory setting is 0-10 VDC. Only place the jumper vertically. The range of the input signal can be specified in software by setting a minimum and a maximum limit. The limits are in percent of the full range. The display value of the input signal may be specified according to its measuring range. For example a pressure sensor has a 4-20 mA output and a pressure range of 0 – 200 Pa. It is possible to transform the input signal into a different dimension by setting the lower and upper measuring range limit according to the features of the sensor device. In our example the display will read 100 for a 12 mA signal. Range values below 100 will have a resolution of 0.5, below 50 of 0.2 and below 25 of 0.1.

Output Configuration

General

An output must be assigned to a function or a control loop using the OP parameter set. Assigning an output to a control function will automatically activate the respective function. Unassigned functions are not active.

Alarm function

The alarm setting defines how the output should respond to a specific alarm condition. In case of an alarm the output may be switched on (100%) or off (0%). The alarm situation takes precedence over operating state and calculated output

signal.

Analog Output

The analog output may be configured with jumpers for 0-10 VDC or 0-20 mA control signals. The jumper is located on the front side of the power part. The drawing on the right indicates the jumper placement for each signal type. The factory setting is 0-10 VDC. Only place the jumper vertically. Only place one jumper for one signal. The signal range can be specified in software by setting a minimum and a maximum limit. The limits are in percent of the full range.

Special functions of the analog output:

Manual Positions the output directly with a set point. The number of positioning steps can be

selected: 2, 10, 100 steps

Dehumidifying (only for 4-pipe systems)

The maximum value is taken of both direct acting PID sequences (Cooling and dehumidifying). Cooling will start to operate if the humidity gets too high, even if there is no cooling need, thus the heating will be forced to come into play, which in turn dehumidifies the air.

VAV In the VAV control sequence, at peak cooling the airflow setpoint is the maximum amount

of air the VAV box is set to deliver. It may be adjusted through the maximum limit on the analog output (OP03). As cooling requirements decrease, airflow dwindles until it reaches its minimum setpoint. This setpoint will be based on the airflow needed at design cooling and is typically 10% to 15% of maximum cooling airflow. Minimum airflow can be adjusted by the minimum limit on the analog output (OP02). When it reaches this minimum, the system is in its dead band and is neither heating nor cooling. As the system moves into heating mode, the airflow rate increases until it reaches the maximum airflow required for heating mode. This is typically 30 to 50% of maximum airflow of cooling mode. The parameter for this is called VAV function: maximum limitation in heating mode (OP05).

Binary Outputs

If OP11 is in the OFF position, DO1 and DO2 may be used as binary outputs. They may be used for binary sequences or other special functions:

Additional functions oft he binary output:

Dehumidifying (only for 4-pipe systems)

Operation State (On if operation state is ON)

Operation State with switch off delay 60s

Output while demand on any output, switch off delay 60s

Indication of the fan symbol

The maximum value is taken of both direct acting sequences of LP1 and LP2 (Cooling and dehumidifying). Cooling will start to operate if the humidity gets too high, even if there is no cooling need, thus the heating will be forced to come into play, which in turn dehumidifies the air.

The output is ON if either comfort or standby mode are active. In energy hold off mode (EHO) the output is off.

The output is ON if either comfort or standby mode are active. In energy hold off mode (EHO) the output is off with a switch off delay of 60s. This is required for fan supported heating or cooling coils with mold protection.

The output is ON if demand exists on any other output. The output switches off with a fixed delay of 60s if there is no more demand. This function is usefull for fan supported heating or cooling devices.

By enabling this function, the fan symbol is shown on the display whenever DO1 is active.

Floating Outputs

Enabling OP11 changes DO1 and DO2 into a floating output for a PID loop. In this case the running time of the actuator needs to be specified. Running time is defined as the time required for the actuator to run from fully open to fully closed or vice versa. Actuators with a fixed running time are recommended. Once fully open or fully closed the running time for the actuator is extended for a full run time cycle. This will allow the actuator position to be synchronized in case it has been moved during off time or an actuator with variable running time was used.

Switching difference on floating output: Use the Switching difference parameter to reduce the switching frequency of the actuator. The actuator will only move, if the difference to the current actuator position is larger than this parameter.
