40 Electrical Connection Multi Flair 6.4 Installing control panel All IP20 control panels have an integrated room temperature sensor. The latter can be used when the control panel is mounted at an optimum indoor location for regulating temperature. All IP54 control panels are supplied with a separate external indoor temperature sensor. OTE! The installation site of the room temperature sensor is crucial for the precise control of indoor temperature. Therefore avoid mounting the sensor in the following locations (refer to Fig. 6-5): next to doors, windows, hatches etc., as intense movement of air can cause incorrect measurements and affect control operation. hot or cold walls (e.g. chimney, outside wall), as wall temperature can cause incorrect measurements and affect control operation. behind curtains and net curtains as the insulating layers of air can cause incorrect measurements. in the direct vicinity to the units' discharge grille as discharge temperature can cause incorrect measurements. If a mounting location for an IP20 control panel is not available, or a IP54 control panel is required, a separate room temperature sensor must be fitted. This automatically disables all temperature sensors fitted in the control panel. * Fig. 6-5: Mounting control panel and room temperature sensor * recommended installation height 40 PR GB Subject to modifications R5-/205

When checking the control inputs and outputs consider that configuration is performed by the manufacturer. Refer to the unit wiring diagram (see inside cover of the unit connection box) for the relevant controller function. Possibly made changes in the configuration by others on site (via MATRIX.PDA service tool or MATRIX.PC service software) can not be considered here Function input MATRIX The input can be assigned with the following functions as required: Window contact Set the jumper on the input terminals. Turn the unit on and change the setpoint as required to activate the fan. Remove the jumper. The fan must switch off, the valves close (unit remains in frost protection monitoring mode).

74 Commissioning Multi Flair 7.9 Functions 7.9. Fan mode The behaviour of the fan control depends on the configured control type and operation mode on the selected control panel. The following fan modes can be set: Manual fan control Automatic fan control Automatic fan control in mute mode The fan switches off irrespective of the selected mode if one of the following errors has occurred: Motor thermal monitoring tripped Insufficient operating data due to sensor error Defective hardware Manual The fan is operated at the pre-set fan speed. The fan speed can be pre-set via the control panel, the building management system or via external modules (e.g. digital input module). Fan stages 3 2 Off Switching difference 00[%] Automatic The fan is regulated depending on the difference from the setpoint (temperature). In mute mode the highest fan speed is blocked. The fan speeds are controlled according to the difference between actual and setpoint readings. Both the size and the time of the existing deviation affect the control behaviour. The number of the available fan speeds depends on the unit type. Parameter: Speed number: speed stage fan Speed number: step fan (only MATRIX 2002) Air change function This function enables the fan to operate irrespective of the selected control mode and to remain switched on even if the setpoint temperature has been reached. The fan speed must be selected manually in this case. This should provide an optimal air change in the room. This function can only be selected using the MATRIX OP50 and MATRIX OP5 control panel or the MATRIX.PC service software. 74 PR GB Subject to modifications R5-/205

75 Multi Flair Commissioning Valves Depending on the selected controller equipment, the integrated valve controller supports valves with on/off control or modulating behaviour. The valves can be controlled in the following modes: Heating Cooling Heating or cooling In order to reach a common starting position the factory set synchronisation moves all connected valves (only with modulating control) every 24 hours to OPE or CLOSE position Condensate pump The condensate pump drains the condensate that forms on cooling units. If required, the condensate pump is switched on by a float switch. When a limit value is exceeded, the fan is switched off, and an error message is displayed on the control panel Standby mode Standby temperatures mode is only available with room temperature control option. This does not regulate the temperature to a fixed setpoint, but instead to a pre-set setpoint range. This setpoint range can only be changed using the MATRIX.PC service software. The stand by mode is active if a room temperature sensor is connected but no room temperature setpoint, i.e. no control panel, is available (e.g. during the construction phase to dry out the building). The standby mode function is terminated if specific room temperature setpoint is set Indoor anti-freeze protection This function ensures a frost-free condition when the unit is switched off. At room temperatures < 4 C, the valve is fully opened and the fan is switched at the lowest fan speed, regardless of the inlet temperature. If room temperatures reaches > 6 C, the valve is closed and fan deactivated. ormal regulation mode is activated. PR GB Subject to modifications R5-/205 75

76 Commissioning Multi Flair Summer / winter compensation This function requires to connect an external sensor. End Temperature Temp. Offset Start Temperature End Temperature This function enables a shift in the room temperature setpoint depending on the ambient temperature. Application example: From 26 C outdoor temperature and on, indoor temperature setpoint must be increased by 0.5 C per C rise of outdoor temperature. The setpoint should not be increased any further if outside air temperature reaches 32 C. Thus 26 C as the start temperature and 32 C as the end temperature should be entered. The setpoint offset is calculated as follows: (End temperature - start temperature) * 0.5 C (the increase per C external temperature increase) (32-26) * 0.5 = 6 * 0.5 = 3 The factory set parameters can only be changed via the MATRIX.PC service software Filter replacement indication This function calculates the filter contamination level using the operation times of the respective fan speeds. The necessary filter replacement message is displayed and entered as a warning only on the MATRIX OP50 or MATRIX OP5 control panel. The filter change message is activated after "service period" or "minimum service interval" is exceeded. Confirmation of the warning is followed by the new calculation of the remaining service period. Upon successful filter replacement the internal run timer counter is reset using the menu selection on the control panel. 76 PR GB Subject to modifications R5-/205
