Page 133: Temperature Adjustment Considerations
TEMPERATURE ADJUSTMENT CONSIDERATIONS The heating and cooling resources are managed on the basis of the temperature values measured by the return or delivery probe depending on the parameter settings. This temperature is compared with the set value (setpoint), and based on the difference, the devices may activate.

Page 136: Setpoint Offset
4.3 Setpoint offset This function allows automatic cooling and heating setpoint variation within a preset range, based on a signal sent to the unit controller. The function monitors in real time the input value (analogue signal, or temperature read by the remote 1 T+H probe, or temperature red by the external T+H probe, or the calculated return temperature), and calculates the offset value based on the parameters.
Page 137 Note: The previous chart shows a condition when the entered P27.27 value is below 0. If the probe selected for compensation fails, the setpoints will assume the non–compensated values as per parameters P50.01 and P50.02. In case of compensation through analogue input, the only available parameters will be the maximum P27.24 and P27.27 offset values, as the minimum and maximum limits correspond to the signal sent to the controller (0–1V, 0–5V, 0.5–4.5V, 0–20mA, 4–20mA).

COOLING 5.1 Cooling in s-MEXT units 5.1.1 Communication with the Mr Slim unit During the management and control of Mr Slim units, it is necessary to use interface cards (PAC-IF013B-E), through which the s-MEXT unit will send commands and request information from the Mr. Slim units. There are 2 possible types of connections for the use of Mr Slim units, depending on the number of them being used with the s- MEXT unit.

Page 142: Minimum Delivery Temperature Limit
5.2 Minimum delivery temperature limit 5.2.1 Objectives Setting a minimum limit to the delivery temperature may be a request justified by the presence, very close to the unit delivery outlet, of devices that are sensitive to relatively low temperatures. The delivery temperature can only fall excessively if there is a sudden decrease in the temperature of the cold coil (evaporation temperature or, more likely, the temperature of the chilled water coming from a chiller).
Page 143: Heating
HEATING 6.1 Heating resources The sources available for ambient air heating are the following: • Heating elements, managed as simple on/off loads. INFORMATION: The activation of the electric heaters forces the demand for ventilation at the maximum speed. This speed is defined as the greater between P10.10 and that generated by the ventilation control logics.
Page 144: Post-Ventilation Function For The Electric Heaters
6.3 Post-ventilation function for the electric heaters This function, available for all the units equipped with electric heaters, is for cooling the electric heaters when the unit is turned off and the electric heaters are still active. When the OFF command is given (at the keyboard, by the supervisor, or remotely), the fan continues to run at nominal speed for a period of time set in the parameter (P23.61).
Page 145: Adjustment With Temperature Provided By The Supervisor
ADJUSTMENT WITH TEMPERATURE PROVIDED BY THE SUPERVISOR INFORMATION: To enable the parameter for this adjustment (P30.09) it will be necessary to enable the supervision. This adjustment is available only for the port BMS1 and compatible only with the Modbus protocol. The function involves use of the temperature from a Supervisor system.

8.2.3 Lower limit There is also an absolute lower limit for dehumidifier operation; it is managed according to a step whose position on the room temperature axis depends on the presence or absence of resources for post-heating, if any. If there are no heat resources available (heaters or hot water coil), the lower limit step refers to the cooling setpoint, as shown in the following figure: Dehumidify (°C)

Page 154: Vapour Production Regulation
9.2.2 Vapour production regulation The production of vapour by the integrated humidifier constantly depends on the humidification demand according to ambient humidity adjustment. The programme adjusts humidity according to the reading of the humidity probe, the humidity setpoint and the humidity differential.
Page 155: Periodic Drain
9.2.6 Periodic drain It is recommended that this function is enabled through parameter P27.16 when using water rich in substances such as humus and slit. The humidifier drains and automatically replaces the water in the cylinder to prevent the accumulation of these substances.
Page 156: Alarm Management
9.2.8 Alarm management The terminal displays the active alarms. The Alarms and Signals relative to humidifier operation are detailed in the controller alarms section. A crucial point of humidifier operation is excess current control. In fact, whenever voltage is applied to the boiler electrodes after a period of shutdown, short but very intense current peaks can be observed.
Page 157: Temperature And Humidity Measurement
10 TEMPERATURE AND HUMIDITY MEASUREMENT 10.1 Return air T+H probe This probe is available for all the units that require humidity control and allows the enabling of the following functions: • dehumidification; • Humidification. It also allows the reading of the humidity, in addition to temperature, and can be used for the calculation of the return temperature. The probe is connected via Modbus to the Fieldbus port defined using the controller parameters at address 128.
Page 158: External T+H Probe
10.4 External T+H Probe This probe is available for all the units. It also allows the reading of the external temperature and humidity. Probe 1 is connected via Modbus to the Fieldbus port defined using the parameter of the controller at address 133. 11 INTERNAL AIR FAN MANAGEMENT 11.1 Introduction The unit is fitted with EC radial evaporating fans.
Page 159: Automatic Speed Regulation Function
11.5 Automatic speed regulation function This function allows to automatically adjust EC radial fan speed. It may follow two logics: • Constant flow rate regulation. • Constant residual ∆P regulation. For these two logics, a differential pressure transducer is used and positioned so as to detect the pressure value used for regulation.
Page 160 When configuring the unit the project flow value and the number of fans in the unit are entered. The programme also requires that the fan flow is never less than the set rated flow. The parameters entry mask is under the “Fan” menu accessible through the “Service” password. The purpose of regulation is to keep the flow rate constant when there is an increase in the loss of load, with reference to the graph below.
Page 161: Constant Residual ∆P Regulation
Constant residual ∆P regulation 11.5.2 The pressure transducer is positioned according to the following figure: Figure 11-5: chart for positioning the pressure taps for the differential pressure probe. The controller adjusts following the chart below: INCREASE speed NO Action DECREASE speed Differential pressure P23.67 Differential...
Page 162 The purpose of regulation is to keep the residual ∆P constant when there is an increase in the counter–pressure, with reference to the following graph. Figure 11-7: constant head fan operation curve Starting from nominal work point (A), the increase in counter-pressure (due, for instance to a damper closing) causes a shift in the fan work point along the curve towards point B, with the ensuing increase in pressure.

Calibration is performed during production testing using the following mask: Fan - Const.
Page 164: Command From Supervisor
11.6 Command from supervisor This function allows direct control of the internal fans of the unit by sending a ventilation command to the controller from the supervision system. The fan speed is changed according to the last command received. This means that if communication fails between the controller and the supervisor, the fans will continue to run at the same speed of the command received before communication failure.
Page 165: Fan Adjustment Based On Temperature (Former Fan Special Function 02)
11.8 Fan adjustment based on temperature (former fan special function 02) Fan speed can be controlled on the basis of: • return temperature; • delivery temperature; • temperature differential (return temperature - delivery temperature). 11.8.1 Fan adjustment based on return temperature This special function permits modulation of the EC fan using the return air (ambient air) probe as the adjustment temperature, at the same time adjusting the actuators using the delivery air temperature.
