4.1 CIRCUIT BOARD SAT 3  CID372005

The SAT3 circuit board is used for extra functions for which inputs and outputs are not included as standard in the control unit of the air handling unit. All outputs are normally open (N.O.). Maximal load: 230VAC – 4A. The circuit board SAT3 allows for signalling of the following by means of a potential-free contact:

• Fan status - O.R. 1

• Dierential pressure alarm - O.R. 2

• Heating demand - O.R.3

• Bypass status - O.R.4

Installation

SAT3 must be plugged onto the control board circuit (see g.1).

Attention: The SAT3 must be plugged in before the circuit is powered. SAT must be plugged in correctly, wrong positioning can damage both circuits permanently.

5.1 OPERATING MODE

There are ve main operating modes. The operating mode determines how the airow or the fan torque is modulated. The default operating mode is Airow control. Exceptions are units equipped with backwards fans without the Constant Air Kit or if Constant Torque mode has been selected in the product setup menu, in both cases it is the fan torque that will be controlled and modulated.

5.0 Functions

In all the operating modes, the supply fan(s) will operate as per the assigned mode and parameters. The exhaust fan(s) will operate according to the chosen percentage of the supply fan (%EXH/SUP ratio). The ve main operating modes are:

• 1 - Airow control:

Flow control involves operating the air handling unit to keep the pre-set airow constant. The speed of the fans is automatically regulated to provide correct airow even if the lters begin to become clogged, air terminals are blocked, etc. Airow control mode is advantageous, since the airow always is exactly as it was from the beginning. It should however be noted that everything that increases the pressure drop in the ventilation system, such as blocking of air terminals and dust accumulating in lters, causes the fans to run at a higher speed. This results in higher power consumption and may also cause discomfort in the form of noise. There are three airow setpoints to be congured by the user (m³h K1, m³h K2, m³h K3).

• 2 - Torque control:

3 torque setpoints to be congured by the user (%TQ K1, %TQ K2, %TQ K3). The setpoint is congured in % of the maximal torque. The torque control allows to vary the fan speed automatically, to provide a variable airow for demand controlled systems (DCV). This allows for demand controlled fan operation or fan optimisation by a BMS system, mostly used in multi zone systems. This operation mode can partially replace the constant pressure control when a duct pressure sensor hasn’t been installed.

• 3 - Demand control 0-10V:

The airow is controlled by a 0-10 V signal. The control signal is connected to terminals K2&GND. The assigned supply airow is set as a percentage of a linear 0-10 V signal. The user denes the link with 4 parameters: Vmin, Vmax, m³h Vmin and m³h Vmax, applied to the following diagram. The demand control mode is also available for modulating fan torque instead of airow (relevant for backwards fans units without Kit CA). The principle is identical to the demand control mode operation with the dierence that Vmin and Vmax are connected to a %TQ instead of m³/h.

• 4 - Pressure control:

The airow automatically varies to provide constant pressure in the ducting system. This type of control is also called VAV control (Variable Air Volume).

Pressure on supply: the airow of the supply fan(s) is modulated to maintain a certain pressure Setting constant. The pressure is measured by a pressure sensor located in the supply air duct. Pressure on exhaust: the airow of the exhaust fan(s) is modulated to maintain a certain pressure Setting constant. The pressure is measured by a pressure sensor located in the extract air duct.

• 5 - MODE OFF :

This stops the AHU

5.2 TEMPERATURE CONTROL

5.3 FREE COOLING RX AND PX

There are several options available on GLOBAL units to ensure a comfortable temperature. The options are controlled either via supply or extract air temperature.

The free cooling function uses the lower temperature of the outside air to cool the building.

Free cooling is realized by means of the integrated 100% modulating bypass of the heat exchanger (PX) or the stepless motor control of the rotary heat exchanger (RX). The optional output O.R.4 on the SAT3 relay indicates the position of the bypass. The contact will open if the bypass is fully closed, or close if the bypass is fully or partially open.

The bypass (PX) or the rotary heat exchanger (RX) can be congured as on/o or modulating. This is congured in ADVANCED SETUP. In modulating mode, the temperature is congured in the base setup and the position of the bypass/stepless motor will modulate in order to maintain the setpoint. The free cooling function is activated automatically. An on/o bypass / stepless motor operates according to the logic below:

Free cooling STARTS if the following conditions are TRUE :

These Settings can be congured in ADVANCED SETUP

Free cooling STOPS if one of the following conditions is TRUE :

Extract Air Temperature

The default temperature control can be changed to Extract temperature control via the advanced setup. The extract air temperature is measured on sensor T2. Extract air control involves keeping a constant temperature in the extract air duct (premises), by controlling the supply air temperature. This provides a uniform temperature in the premises regardless of the load. The internal sensor T2 can be replaced with the optional external room temperature sensor (CID370042).

Temperature sensor positioning :

• The outdoor temperature (sensor T1) is lower

than the extract air temperature (sensor T2)

• The outdoor temperature (sensor T1) is

higher than 15°C.

• The extract air temperature (sensor T2) is

higher than 22°C.

• The outdoor temperature (sensor T1) is higher

than the extract air temperature (sensor T2).

• The outdoor temperature (sensor T1) is

lower than 14°C.

• The extract air temperature (sensor T2) is

lower than 20°C.

Supply Air Temperature

Supply temperature control is the default setting. This involves keeping a constant supply air temperature without consideration to the load in the premises. The supply air temperature is measured on sensor T5.

Operation and maintenance instructions – v2.8.8 & 2.7.3

5.5 CHANGE OVER FUNCTION

The TAC5 controller allows for the control of both cooling and heating coil. Both coils are equipped with their motorised 3-way valves. The oset between the measured temperature (supply air or extract air, to be congured) and the setpoint will determine if heating or cooling is automatically activated. When the unit is equipped with both a cooling and a heating coil, only one setpoint has to be congured: Comfort temperature. The neutral band prevents the cooling and heating systems from counteracting each other. The high neutral band is added to the comfort setpoint for the activation of the cooling function and the low neutral band is subtracted from the comfort setpoint for the activation of the heating function. Both high and low neutral bands have to be congured in the advanced setup.

4 PIPE AUTOMATIC CHANGE OVER

5.4 COOLING RECOVERY RX ONLY

Cooling recovery STARTS if the following condition is TRUE :

• The outdoor temperature (sensor T1) is higher than the extract air temperature (sensor T2).

The cooling recovery function uses the lower extract air temperature to cool down the fresh air. The function is not congurable. If there is a cooling load in the building and the temperature in the extract air is lower than the outdoor air temperature, the heat exchanger shall be automatically controlled to operate at maximal speed. The temperature setpoint is congured in the base setup and the rotary heat exchanger will modulate in order to maintain the setpoint. The cooling recovery operates according to the logic below:

Operation and maintenance instructions – v2.8.8 & 2.7.3

• 1 - Reduced supply air ow :

The heat exchanger is supplied with a frost protection sensor on the exhaust air (T3). If the exhaust air temperature (T3) is >1°C and <+5°C :

• In airow control mode and demand control, the supply air ow will modulate between 100% and 33% (AFlow)of the setpoint (AFn)

• In pressure control mode, the supply air pressure will modulate between 100% and 50% (AFlow) of the setpoint (AFn) If the exhaust air temperature (T3) is <1°C, the supply air fans will stop until the exhaust air temperature (T3) is >2°C for 5 minutes.

• 2 - Modulating bypass :

The modulating bypass is controlled by the exhaust temperature sensor (T3). If:

• Exhaust temperature (T3) >+1°C: bypass closed or controlled by free cooling function

• Exhaust temperature (T3) ≤ +1°C: bypass will modulate for the exhaust temperature (T3) to exceed +1°C. The corresponding supply air temperature will drop due to a lower airow through the heat exchanger

• 3 - Electrical preheating coil (accessory) :

If an electrical pre-heating coil (KWin) is installed and congured, the pre-heating coil (KWin) will modulate so the exhaust temperature is +1°C.

• 4 - Dierential pressure measurement (Cold climate option) :

For cold climate conditions (≥-20C), the unit is equipped with a dierential pressure sensor mounted on the heat exchanger. The pressure sensor detects when the pressure drop, due to frost, has become too high. In critical conditions, the supply air ow will be paused for a short time, to allow for defrosting. The frost protection strategy (down regulation supply airow, modulating bypass or electrical pre-heating) will still be used as a rst step. The defrost function will only be active if the frost protection strategy is not sucient.

5.6 FROST PROTECTION

The frost protection function is always active if the heating coil has been correctly congured in the product setup. The monitoring function uses the temperature sensor T4 for the integrated coil (IBA) or the temperature sensor T7 for the external coil (EBA). The function is

In order to protect the rotary heat exchanger from freezing, the strategy for frost protection consists of modulating the speed of the rotating heat exchanger, which is linked to the outdoor air temperature (sensor T1).

There are three strategies to protect the plate heat exchanger from freezing :

activated when the surface temperature of the coil drops below 5°C. Under these conditions the pump output is activated and the three-way valve output will be 100%. If aer 15 minutes the surface temperature has not risen, the unit will shut down and generate a frost alarm.

If the outdoor air temperature < T°AF (default -9°C): the rotation speed of the heat exchanger is reduced to avoid the risk of icing. To exit this anti-frost protection: T°(T1) ≥ T°AF for 5 minutes.

These Settings can be congured in ADVANCED SETUP.

There are four strategies: down control of the supply air volume, modulating by-pass control, modulation of capacity of a preheating coil, dierential pressure measurement (cold climate option). If non of these measures are eective, the air handling unit can be stopped by limting the minimal supply air temperature. When the Frost protection cycle is active, it will be indicated on the HMI. The congurable temperatures are outdoor temperatures.

Operation and maintenance instructions – v2.8.8 & 2.7.3

Attention : before handling and/or opening the access panels it is compulsory to shut down the unit and disconnect the power supply using the general switch located on the front panel. Do not isolate the power supply whilst the unit is running. If KWin and\or KWout are installed, then isolate the corresponding power supplies.

Regular maintenance is essential to guarantee good operation of the air handling unit and a long service life. The maintenance frequency will depend on the application and on the actual environment conditions but the following are general guidelines:

Replace the lters with a kit of replacement lters.

- Check for any alarms indicated on the control device. In case of an alarm refer to troubleshooting section.

- Check the state of lter clogging. The control device allows a pre-dened ‘lter alarm’ threshold to be set. Replace lters if necessary. Filters that are too clogged can generate the following problems:

- Insucient ventilation

- Excessive increase of fan rotation speed

- Excessive sound levels

- Excessive power consumption (power consumption will increase exponentially to an increase in pressure drop, for a constant airow)

- Unltered air passing through the heat exchanger (risk of clogging) and into ventilated rooms.

The list of replacement lter kits for each unit can be downloaded from our website.

- Inspection and cleaning of the inside of the unit:

• Vacuum clean any accumulations of dust in the unit.

• Inspect and gently vacuum clean the heat exchanger if necessary. Use a brush to protect the ns.

• Clean any condensation stains

• For PX units, clean any accumulations in the drain pan.

7.1 ONCE THE UNIT OPERATES IN NORMAL CONDITION

7.2 EVERY 3 MONTHS

7.0 Preventive maintenance

Operation and maintenance instructions – v2.8.8 & 2.7.3

1. For rotary heat exchanger (RX) units, check the brush seals on the rotary heat exchanger along the perimeter in contact with the frame:

If necessary, bring the brush seals closer to the exchanger to ensure good sealing.

2. For RX units, check the tension of the driving belt on the rotating heat exchanger. If there is no tension or if the belt is damaged, please, contact the service department for a belt replacement.

Ideally the heat exchanger should be cleaned using vacuum cleaner with a so nozzle to prevent damaging the air passages in the rotor. Turn the rotor by hand to enable you to vacuum clean its entire surface. If the heat exchanger is substantially fouled, it can be blown clean with compressed air.

3. For plate heat exchanger (PX) units:

• Clean the drain pan

• Clean the inside of the bypass. To access the interior of the bypass it is necessary to force it open, proceed as follows: place a jumper between terminals IN4 and +12V on the TAC5 circuit board. The bypass is now open, regardless of the temperature conditions.

• Remember to remove the jumper between terminals IN4 and +12V once cleaning of bypass is done.

• Always clean against the direction of the airow.

• Cleaning must only be done by blowing with compressed air, vacuum cleaning with a so nozzle or through wet cleaning with water and/or solvent. Before you begin cleaning, cover adjacent functional sections to protect them. If cleaning solvent is used, do not use solvent that will corrode aluminium or copper.

4. Fan maintenance:

Check again whether the power supply is shut down and fans are not running.

Inspect and clean the fan impellers to remove any dirt deposits, be careful not to alter the impeller balance (do not remove balancing clips). Check the impeller to make sure that it is not out of balance. Clean or brush o the fan motor. It can also be cleaned by carefully wiping it with a damp cloth that has been dipped in a solution of water and detergent. Clean the fan space, if needed. Remove the fans if necessary.

5. Check seals on the unit:

Ensure that the side access panels are fully closed and that the seals are intact. Replace if necessary.

8.0 Troubleshooting

- Conditions:

- Causes:

•

Failure of fan Fx. This problem is usually caused by the fan motor.

If not, the failure may be caused by an internal cable (control or power) or by the TAC5 circuit.

- Eects:

The TAC5 control board generates and reports 18 types of alarms.

The alarms are subdivided into auto resetting and non-auto resetting alarms. For the latter, a reset will be necessary once the problem has been resolved.

For each type of alarm, a full text description will be displayed on the user interface depending on the alarm type:

- Activation of contact relay (NC or NO contact)- AL 1

- Activation of SAT3 OR1 in case of pressure alarm, provided that the optional module SAT 3 is installed on the control board.

- “Alarm”, “Pa” and “AF” activated LED’s on control board

- Alarm on user interface.

- Alarm communication with networking modules provided that an optional communication module (Modbus RTU, MODBUS TCP/IP, and KNX) is installed on the TAC5 control board.

Operation and maintenance instructions – v2.8.8 & 2.7.3

- Conditions:

•

Mode Airow control or Demand control: during the initialization of the pressure alarm. In this case, the unit must have

forward fans or backward fans with kit CA.

•

Mode Pressure control: during the initialization of the pressure reference via airow

- Causes:

The reference pressure (Paref) cannot be identied and the fans are stopped. 4 possibilities:

1. Actual airow < requested airow: The requested working point is ‘too high’ (too high pressure loss) for the maximal available pressure at the requested airow for this fan.

2. Actual airow > requested airow: the nominal airow requested to initialize the pressure alarm cannot be reached because the lower limit of the fan’s operating zone has been reached.

3. Very unstable pressure (pumping).

4. Assigned airow not reached aer 3 minutes.

If this occurs during initializing an alarm pressure, there are 2 options:

1. No action is taken: the control will operate without a pressure alarm.

2. Corrective action is taken (change the working point to one located in the working zone of the fan, by reducing the pressure system, modifying the nominal airow…) and restart the setup operation.

If this occurs during initializing of the assignment pressure in pressure control mode: Corrective action must be taken (change the working point to one located in the working zone of the fan, by reducing the pressure system, modifying the nominal airow …) and restart the setup operation.
