2 Philosophy of air handling units
2.1 Overview
Climatix OEM controller product range
Climatix 6xx controller product range
With the Climatic controller product range for OEM, Siemens is supporting the trend within the industry to integrate applications for air conditioning and refrigera­tion technology into the devices at the factory and to lower in this way the costs of plant installation and commissioning.
The Climatix product range covers all application segments: From standard control­lers for simple, cost-optimized HVAC applications such as fan coils to more chal­lenging, communicating applications, up to and including freely programmable controllers for complex solutions using AHU or chillers that demand a maximum amount of flexibility for communications and extensions.
All Climatix POL6xx controllers are freely programmable and can be programmed accordingly for the corresponding use such as ventilation, refrigeration or district heating.
Various standard applications were created to help OEM customers speed up time­to-market and benefit from our application knowledge and experience in integrating into the building automation and control system.
The applications are based on years of experience in the corresponding application segments, are checked and tested and equipped with the required communication interfaces such as BACnet, LON and Modbus. The standardization in turn significantly lowers costs at OEM, reduces support exp­enses as well and guarantees integration into Siemens building automation and control systems.
2.2 Properties
Climatix standard AHU application
The application includes all standard as well as special ventilation functions which can be selected for the OEM and defined using the operator unit (HMI).
The OEM loads the generated parameter file at the end of line test so that the AHUs are ready to install. Authorized personnel are also able to enable additional functions in the field to make it possible to add any desired extensions. The AHU standard application stands out with its flexible hardware and software, but also thanks to the standardization of integration.

2.3 Safety
All equipment that is connected to the system must be CE marked and comply with the Machine Safety Directive.
2.3.1 Requirements regarding personnel for installation and
start-up
Installation and start-up of POL 63X may only be carried out by qualified personnel who have relevant technical expertise and who are well acquainted with all the safety and installation regulations.
2.3.2 Safety regulations
The following safety regulations do not relate solely to POL 63X but also to the regulator’s surroundings (e.g. control panel) and the technical plant in the property.
Observe all safety directions and comply with the corresponding general safety regulations in order to prevent personal injury and damage to property.
• Safety devices may not be removed, bypassed or taken out of operation.
• Apparatus and system components may only be used in a technically fault-free
state. Faults that can affect safety must be rectified immediately.
• Observe the required safety instructions against excessively high contact
voltages.
• The plant may not be in operation if the standard safety devices are out of
operation or if their effects are influenced in some other way.
• All handling that affects the prescribed disconnection of the protective extra-low
voltage (AC 24 V) must be avoided.
• Disconnect the supply voltage before opening the apparatus cabinet. Never
work when the power is on!
• Avoid electromagnetic and other interference voltages in signal and connection
cables.
• Assembly and installation of system and plant components may only be
performed in accordance with corresponding installation instructions and instructions for use.
• The following equipment must be protected against static charging: electronic
components, open printed circuit boards, freely accessible connectors and apparatus components that are connected with the internal connection.
In this context, also observe necessary protective measures such as earthing, potential equalisation, conducting surfaces (avoid highly insulating materials), etc.

Packing
Transportation
Storage
Cleaning
Faults
2.4 Packing, transport and storage
The required packing of the system for storage and transport is dependent on the mechanical and climate conditions.
Use the original packaging from Siemens or from the supplier when mechanical and climate conditions have an impact on transport.
During transport under particularly difficult conditions, a special package must be used.
If the equipment is not to be installed immediately, store it in a well ventilated area, protected against high temperatures, humidity, dust and metal particles.
• For storage and transport, the limit values specified in data sheet CE2Q3226 always apply. Contact your supplier or Siemens in the event of any uncertainty.
• Damage that arises as a result of incorrect packing, storage or transport is not the responsibility of Siemens.
2.5 Maintenance and service
All that is required to maintain POL63x is regular cleaning. System components that are arranged within the control panel are most easily separated from dust and dirt in conjunction with the prescribed maintenance checks.
Diagnostics, the rectifying of faults and restarting may only be carried out by authorised staff. This also applies to work within the control panel (e.g. inspections, replacing fuses). In the event of unauthorised interventions, Siemens cannot undertake to honour any guarantees. The responsibility for any damage that occurs in the system and any consequential damage rests with whoever caused the damage.
2.6 Environmental protection and waste

Waste management
management
Process unit POL 63X has no negative impact on the environment.
The apparatus includes electrical and electronic components and when discarded must not be handled together with household waste. Always observe local regu-
lations!

Scheduler function
Program time switch catalog
Select days of the week
Please note: The room unit does not have an internal clock. The precise time is
periodically synchronized with the controller (master).
The weekly and daily schedule for the time switch catalog (so-called "scheduler") can be programmed:
• for all 7 days of the week.
• Daily with up to 6 switching entries (referred to as "Entry")
You can do the following when setting up the entries
• determine a switching time and
• select the state to be run in Auto mode.
Possible state assignments (e.g. 0=Off, 1=EcoSt1, 2=ComfSt1, etc.) are predefine­d as part of the controller configuration. A max. 7 states are possible.
The selected operation is automatically run at the defined time after the entry is setup.
The following button assignments are enabled when programming the scheduler:
• PROG —> Cancel.
• OK. —> Confirm.
The workflow includes explanations of the individual steps from a technical view­point. As a practical matter, individual steps may not be needed, while others must be repeated, etc. As a result, we are listing an example in this section that illus­trates a practical example on programming a room unit.

3. Conduct weekdays through day 7 as per step 2.
4. 1 time (!) press the plus button.
You now see the selected days; a flashing bar appears above the numbers.
5. Confirm selected weekdays: 1 time (!) press OK.
The display changes to the first entry page, the state is "00X", time is 00:00 :Do not change the time for this entry!
Three entries per day are prepared and may vary depending on the configured plant, e.g. State 001 at 00:00 am, state 002 at 08:00 am, state 001 at 6:00 pm. The entries do not need to be entered in chronological order. The following illustrates how to create a new (the fourth) entry.

5.1.2 Summer Winter changeover
Prerequisite
Function
None.
It decides whether the plant is in summer or winter operation based on various op­tions (hardware input, date, temperature). This information is required (as an op­tion) to shut down humidification in summer, to changeover the Combi Coils and to changeover temperature control (Tmp control mode = RmSplyC Su or RtSplyC Su).
A hardware input enabled for the changeover (Main Index > Configuration > Con­figuration 1 > Su/Wi input = Yes) has the highest priority (Signal 1 = Summer).
The temperature or date can affect the changeover depending on parameteriza­tion. Both criteria must be met when both are enabled. There is no changeover and the plant in continuously in winter operation when no criterion is enabled.

5.3.2 Supply / Exhaust damper
Prerequisite
Air and exhaust air dampers are enabled and preconfigured in configuration 1, con­figuration 2 and configuration I/Os.
Function
Per settings outside and exhaust air damper open at plant start and close at plant stop. Damper opening times can be defined separately. A common default period can be set if no damper feedback exists. The damper command can still be kept at pending for a feedback alarm.
Only the output for the outside air damper is enabled if two dampers are enabled as combined. This is also true for triggering feedback alarms for the exhaust air damper, if a separate feedback per damper is enabled.
Outside damper is forced by the supply fan. Exhaust damper is forced by the exhaust fan. If combined damper is selected, then the output for ouside damper is forced by both supply fan or exhaust fan. Take care if for example Firemode RunExh is used.

Setpoint compensation during summer
– An outside air temperature sensor must be available:
Main Index > Configuration > Configuration 1 > Outside tmp sensor = Yes.
– Summer/winter compensation must be enabled:
Main Index > Configuration > Configuration 2 > Fancomp Outsidetmp = Yes.

Setpoint compensation during the winter.
Parameterization
– Main Index > Unit > Fan Control > Summer comp – Main Index > Unit > Fan Control > Winter Comp
Parameter Range Function Outside tmp start -64…64 [°C] Outside air temperature at which point the compensation begins to
act.
Outside tmp end -64…64 [°C] Outside air temperature by which the maximum (summer) or mini-
mum setpoint is reached.
Delta -100…100 [%] Fan setpoint compensation relating to the maximum allowed fan
compensation (See Fan compensation as well).
Note
Setpoint compensation is not undertaken during the summer and winter when the outside air temperature sensor fails. Minus value means that the fan is decreased, plus value means that the fan is increased. For Fan control mode = Direct, DirectVar, the delta must be set to -100% or 100% due to that a switch up or down takes place when the total added compensations is above 90% (switch back at 10%), but could be less if other compensations is active.

– Maximum compensation = 1000 + 200 – 500 = 700 [Pa] – Compensation setpoint = Setpoint stage1 + 80 % of maximum compensation.
= 500 + 700 * 0,8 = 500 + 560 = 1060 [Pa]
– Maximum possible setpoint = Stage3 setpoint + max force.

∑ comp down 30% Fan control mode Pressure TSP steps 3 Stage1 Setpoint 500 Pa Stage2 Setpoint 800 Pa Stage3 Setpoint 1000 Pa Max forcing 200 Pa Active stage setpoint Stage2, 800 Pa
– Maximum compensation 1000 Pa + 200 Pa – 500 Pa = 700 Pa. – Setpoint = Setpoint stage2 - 30 % of maximum compensation.
– = 800 - 700 * 0.3 = 800 - 210 = 590 [Pa] – Minimum possible setpoint = Stage 1 setpoint = 500 Pa, since the setpoint com-

The fan speed (stage) is reduced when all available heating registers are operating at 100% during heating. This heats up the discharged air.
The fan speed (stage) is increased if all available cooling registers are operating at 100 % (Sequence fan clg = Clg-Fan) during cooling. This cools down the dis­charged air. The fan speed (stage) is first increased during the sequence fan clg = Fan-Clg and the first cooling register is switched on.

setpoint – dead zone. Controller dead zone clg: Setpoint = Supply air heating setpoint + dead zone. Or if sequence is placed last (Clg-Fan): Supply air cooling setpoint + dead zone
Heating example
– Calculated supply air setpoint for heating register: 22 °C. – Dead zone for the fan heating controller (dead zone): 2 °C.
---> Effective setpoint for the controller = 22 °C – 2 °C = 20 °C.

Ensures that the fans are only influenced, if the heating register does not supply the required output. This function not required when the heating register is suffi­ciently sized.
Calculation
– Setpoint supply air pressure: 80 Pa (maximum possible setpoint = Setpoint of
the maximum enabled stage + Max forcing, e.g. = 120 Pa). – Maximum allowable fan compensation (100 % compensation): 40 Pa. – Controller output: 50 %.
---> New setpoint: 80 Pa – (40 Pa * 50 %) = 60 Pa (Not exactly true, see Fancomp for exactly calculation!!!, this text is used on several places!!)
The fan stage is reduced by reducing the setpoint. The air volume to be heated at the heating register becomes smaller and the discharge air temperature increases.
Cooling example
Switching sequence fan clg: Clg-Fan
– Calculated supply air setpoint for cooling register: 24 ℃. – Dead zone for the fan cooling controller (dead zone): 2 °C.
---> Effective setpoint for the controller = 22 °C – 2 °C = 24 °C.
Ensures that the fans are only influenced, if the cooling register does not supply the required output. This function not required when the cooling is sufficiently sized.
Switching sequence fan clg: Fan-Clg
– Calculated supply air setpoint for cooling: 24 �. – Calculated supply air setpoint for heating register: 22 °C. – Dead zone for the fan cooling controller (dead zone): 1 °C.
---> Effective setpoint for the controller: 22 °C + 1 °C = 23 °C.
Ensure that fans are influence prior to the start of the cooling register. This function can also be used if no coolingregister is avalible. You don’t get colder air but you have better comfort due to that the air volume is increased.
Calculation
– Setpoint supply air pressure: 80 Pa (maximum possible setpoint = Setpoint of
the maximum enabled stage + Max Force, e.g. = 120 Pa). – Maximum allowable fan compensation (100 % compensation): 40 Pa. – Controller output: 50 %.
---> New setpoint: 80 Pa + (40 Pa * 50 %) = 100 Pa.

Parameter Range Function Combi Coil – None
– 1 output – 2 outputs
Function
A common register is used for heating and cooling.
This setting determines whether it is a 2 (1Output) or 4 (2Outputs) line CombiCoil.
For the CombiCoil with one output, the input for summer-winter changeover should be enabled in all cases so that the information on summer or winter operation is available. (Configuration 1 > Su-wi input = Yes)
The heating register is exclusively active during the winter; the cooling register ex­clusively during the summer.
The various control settings can be made separately for heating and cooling.
If an additional electrical register is activated, it acts as a second heating register during the winter and a normal heating register during the summer. This makes it possible to heating as needed during the summer.
Output for heating is used for both heating and cooling.
The summer-winter changeover is not used for Combicoil with 2 outputs, but the heating output and cooling can never be active at the same time.
For both 1 output and 2 output mode are the frost controller and the frost alarm deactivated in summer, or if the coolingvalave is open.
Only one output for pump is used (heating), but the pump functionallity must be enabled even for cooling if also cooling should control the output.

Function
Parameterization
• Position Damper-Htg: For heating, the mixed air damper is deployed to the maximum allowable recirculating position (depends on Min FreshAir), before the subsequent heating register starts.
• Position Htg-Damper: For heating, the heating register is first deployed to full load prior the mixed air damper control starts. The startup function for the mixed air damper control must be disabled (StartupTime = 0 s), since otherwise the heating register starts off directly at 100%& output.
Mixed air damper control is used for heat or cooling recovery. The direction of control action (normal/inverse) and a minimum ration of fresh air can be set. The plant can be started for a set period at full recirculation in depend­ence on the outside air temperature.
Mixed damper is forced to full return air if: – Night unoccupied (temperaturstart) heat and cool – OSSTP/Boost

Startup behavior
The mixed air damper is fully opened during the startup period for outside air tem­perature < Startup temp at startup. The controller determines the present position after this period expires.
If heat demand exists at startup, the heating register is started in parallel, and after successful startup, the mixed air controller for heat recovery deploys to the maxi­mum allowable position (100% - MinFreshAir).

Function
Frost protection type is enabled: Master Index > Configuration > Configuration 2, Heat recovery frost <> No
• Temperature frost protection: Detects icing using a temperature sensor in the water exchanger if selected as water or in exhaust air if selected as plate or wheel. This applies for the following settings: Heat recovery frost = Detector, sensor or Dtctr+Snsr.
• Air-side frost protection: Detects icing using a pressure sensor. This applies for the following settings: Heat recovery frost = PressSnsr und Pres+Dtctr.
– For output Frost controller > Output recovery ---> The output follows the recov-
ery.
– For output Frost controller < Output recovery ---> The output follows the frost
controller.
– Controller is disabled when the sensor fails.
The heat recovery controller goes to 100 % output signal as soon as the frost con­troller is no longer enabled, when the subsequent heating register was enabled during frost control.
