3. ROOM AIR TEMPERATURE CONTROL Room temperature is regulated with following devices: ²²Compressors, ²²Additional heating hot water coil electric coil gas burne ²²Economizer: 2 or 3 dampers ²²Energy recovery system 2 set points can be managed, one for summer mode and one for winter mode. 3.1. SUMMER/WINTER SWITCHING To transition from summer mode to winter mode (and vice versa), proceed as follows: 1.
8 SysAer English 3.2.1. KEYING ON/OFF: Select UNIT ON/OFF from the main menu and press ENTER: pressing the ENTER key on the display, you switch the unit ON and OFF. If the unit is switched OFF via the display, none of the other ON/OFF procedures can be used to switch it back ON. If the unit is OFF, all unit functions and its various controls are disabled, except smoke detection. 3.2.2.
SysAer 9 English 3.3. COMPRESSOR CONTROL The number of compressors and circuits depends on unit configuration. Compressors ON/ OFF is controlled by the room air temperature (RAT). The compressors will not work as long as they are locked in the Service menu (P1 and P2). Operation with 2 Compressors (1/2 circuit) with proportional (P) regulation Dead zone / 2 C1 C2 C1 C2 Room Temp.
10 SysAer English 3.3.2. COMPRESSOR CYCLING The compressor cycling is driven by different delays: ²²Compressor start-up delay after main blower has been started: the compressor will switch ON only when the blower is ON for about 10 seconds. ²²Minimum compressor OFF-time: it makes sure that the compressor stays OFF for a while before it is switched ON again.
3.6.1. SUMMER FREECOOLING The summer freecooling is allowed only if: Outdoor Temp < Room temperature – Freecooling/heating differential, to ensure that outdoor air is cold enough to cool room air. Economizer English SysAer 11 compressor operation Room Temp. 100% 0% FreeC_Diff. The opening of the external damper is controlled by the room air temperature as illustrated in the following figure.
12 SysAer English 3.6.4. NATURAL COOLING COMPRESSOR OPERATION In some cases, the natural cooling conditions are filled but the thermal load of the building does not cool down the building enough. In these conditions, the thermodynamic circuits are used as assistance for natural cooling. In order to protect the thermodynamic circuit, a limited number of compressors can operate: SyAer 55 - 65 - 80 - 95 - 105 - 120 - 140 +1°C 2 1 0 1/2 OAT SyAer 160 - 190 - 210 Economizer +1°C FreeH_Diff.
SysAer 13 The enthalpy-based freecooling and freeheating control feature manages external damper opening based on internal and external enthalpy conditions. With room temperature and air humidity, the controller calculates the room enthalpy (see the Inputs/Outputs menu), with external (outdoor) temperature and humidity, the controller calculates the outdoor enthalpy; and with the temperature and Humidity control set points, it calculates the enthalpy set point.
English 14 SysAer 3.7. THREE DAMPERS ECONOMIZER OPTION The return blower is a part of the 3-Damper economizer option. This fan is controlled in the same way as the main blast fan. If the return blower cuts out, the unit is immediately stopped. 3.8. SUPPLY AIR TEMPERATURE MINIMUM LIMIT The Supply air temperature minimum limit protects the room against sudden drops in temperature and cold air draughts.
SysAer 15 The active recovery is managed by a third party controller but the operating order and operating mode are managed by the main controller.
16 SysAer English 3.10.2. SECONDARY CONTROLLER The TRECO is authorized to start up if the mix air temperature (MAT) is: ²²greater than 5°C in winter ²²less than 40°C in winter If these conditions are not activated ²²TRECO does not start up. ²²An "out of range" message is displayed on the home page. ²²No error message is sent to the main regulator. 3.10.3. OPERATING LIMITS The active recovery controller manages the operating limits of the unit.
SysAer 17 When an auxiliary heating device is present (electrical heaters, hot water coil or gas burner), the management in heating mode related to the compressors can be configured: Via the SERVICE menu, an outdoor air temperature can be set to configure the auxiliary heating element as an extra heater (standard) or to replace the thermodynamic heating.
18 SysAer English 3.11.1. AUXILIARY ELECTRICAL HEATING ELEMENTS This function is only available with the Electrical Heaters (2 stages) option. Auxiliary electrical heating elements are controlled by room air temperature as illustrated in the figure below provided the following conditions are met: ²²The unit is in winter mode ²²Electrical Heaters 1 and 2 are enabled (via the Service menu) EH1 compressor operation EH2 Room Temp. EH_Diff Comp_Diff EH_Offset Winter Setpoint 3.11.2.
SysAer 19 In winter mode, a 0-10V output controls the gas burner capacity according to the figure below: compressor operation Room Temp. 100% 0% Gas_Diff Comp_Diff Gas_Offset Winter Setpoint Maximum Supply Air Temperature limitation If the supplied air is too high, this function can proportionally reduce the burner capacity as the figure below: Normal capacity Room Temp. 0% Gas_Supply_Diff Gas Supply Setpoint The supply setpoint is set to 65°C and the differential to 10°C.
20 SysAer English 3.11.4. GAS BURNER TWO STAGE In Winter mode, two contacts control the gas burner stages as shown in the following diagram: Stage 2 compressor operation Stage 1 Room Temp.
SysAer 21 Set point compensation allows saving energy when external temperature values are particularly unfavourable considering the demands of the room to be controlled. The compensation can also be used to increase the comfort. Compensation varies the control set point according to external temperature. This function is available with the external air temperature sensor. Set point compensation differs between winter mode and summer mode in terms of the type of action and the parameters employed.
22 SysAer English Winter Compensation Winter set point compensation is enabled when the following conditions are encountered: the unit is in winter mode STPCOMP Compensation set point [°C] COMPM Maximum compensation [°C] DIFFC Compensation differential [°C] TEXT External temperature [°C] Compensation - Positive differential Example with manual Heating setpoint = 21°C Heating STP 21°C STPCOMP (10°C) COMPM (2°C) COMPM 19°C TEXT [°C] DIFFC (+10°C) TEXT [°C] DIFFC (0°C) 0°C Compensation - N
5. SMOKE DETECTOR The smoke detector is an option. When smoke is detected in the room air, the exhaust blower and the Economizer (external damper) are managed separately via the Service menu. The unit goes into override shutdown, the main and return fan are stopped but the economizer can be configured open or closed depending on the legislation applicable in the country of installation. 6. SCHEDULING This feature is only available if the board has a clock card fitted.
24 SysAer English 6.2. DAILY SCHEDULING The daily scheduling can be managed by two different ways: ²²ON/OFF ²²Unoccupied mode For both options it is necessary to configure a time band with the Start and End hours, that determines 2 zones: inside and outside the band. 6.3. ON/OFF When the hour is inside the band (between Start and End hours), the unit is switched ON. When the hour is outside the band, the unit is switched OFF.
7. USER INTERFACE The terminal is a 6-button, 4-line x 20-character LCD model, which can display text in various sizes and icons. Alarm Up Prog Enter Escape Down 7.1.

SysAer 27 7.5.1. PRINCIPLE 7.5.1.1. SHAREDE DISPLAY When an installation is composed of many units (in different zones/groups or not), it is possible to connect all the Rooftops together and display each unit parameters using only one interface for the whole installation. 7.5.1.2. MASTER/SLAVE Keeping the unique display, it is also possible to configure the network in Master/Slave.
28 SysAer English Rx-/Tx- Rx+/Tx+ GND Touche de programmation J10 J11 Carte d’horloge FUSIBLE In PLAN, it is possible to connect up to 32 elements (controllers or terminals) identified by their individual address from 1 to 31 for controllers and 1 to 32 for terminals (displays). The 32nd unit must always be a terminal. Be careful: terminals and controllers use the same type of address, so all PLAN elements must have different addresses.
7.6. ADDRESSES CONFIGURATION By default, the controllers are always configured with the PLAN address 1, while the terminals have the address 32. The configuration of the addresses of the controllers and the terminals is done with the following procedure: 1. To modify the controller address, the terminal must have the address 0. To modify the terminal address: ²²Connect it to a non power supply controller. ²²Disconnect the controller from any PLAN connection ( J11 plug).
30 SysAer English Share the terminal for all the controllers: ²²The simplest way to configure a PLAN network is to give to the controllers the addresses from 1 to x and to give to the display(s) the addresses 32, 31, 30 …. ²²Connect the 0-address display to the controller previously chosen (powered or not).
²²In the display address of Trm1, put the address of the display (32 for the example). Press ENTER.
