5 - ACCESSORIES 5. - 3-WAY VALVE + BY-PASS Code 70600088. This valve kit can be mounted on all models and is obligatory for cold water use. If this valve is not installed there is a risk of the condensate tray overflowing when the machine is switched off by the thermostat or if the condensate pump breaks down. An auxiliary condensate tray (for the valve) is delivered as standard with the units. For the -pipe versions, kits are required. Characteristics: - Connection: /" male gas (the valve is supplied with the connections for installation directly on the unit s outlet). - Kvs:.6. - "On/Off" 30V thermal actuator. - Open time: 3 min. 5. - REMOTE CONTROLS (for the wire remote control version) 7050076 Manual remote control Control on valve (s) Control on cooling valve + electrical resistance 705005 RCC 0 automatic remote control for -pipe units 705005 RCC 0 automatic remote control for -pipe units + electrical resistance or -pipe 7050053 Change/over sensor or air recirculation with bracket for RCC 705005 Air temperature sensor in box for RCC CWX 3 B CWX 3 BE CWX 3 BW CWX 5 B CWX 5 BE CWX 5 BW Note: "On-Off" action on valve, 30 VAC (accessory). A - MANUAL REMOTE CONTROL Code 7050076. The operating mode is selected manually by a switch on the front of the control unit. Technology : electromechanic. Power supply : 30 Vac Set-point adjustment range: 8 / 30 C (possibility of mechanical limitation by jumpers on the knob) "On-Off" action Control differential : K Operating temperature : 0 / 50 C Relative humidity : < 95% Protection class : cl. II IP :30 Colour : White RAL 9003 Operating switch with fan speed selection Temperature setting knob Heating / cooling selector switch 6
B - AUTOMATIC REMOTE CONTROLS Type RCC 0 - code 705005 and type RCC 0 - code 705005 Selection of the operating mode is done automatically. For the -pipe units capable of heating and cooling operation, a change-over sensor must be connected (accessory, code 7050053) to the installation on the water piping. This change-over sensor can be replaced by a potential-free contact (not supplied), the closing of which causes changeover to cooling mode. There is a possibility to connect a remote air temperature sensor, bare (accessory, code 7050053) or box mounted (accessory, code 705005). Permanent or slaved ventilation. Mode change is possible (Eco or Stand-by) by an external potential-free contact (not supplied). Technology : electronic. Power supply : 30 Vac Set-point adjustment range: 8 / 30 C (possibility of mechanical limitation by jumpers on the knob) "On-Off" action Heating differential : adjustable or K Cooling differential : adjustable 0.5 or K Neutral zone (on RCC 0) : adjustable or 5 K Setpoint in "Eco" mode : 6 C in heating mode 8 C in cooling mode Setpoint in "Standby" : 8 C in heating mode Operating temperature : 0 / 50 C Relative humidity : < 95% Protection class : cl. II IP :30 Colour : White RAL 9003 Heating on indicator light Ventilation on indicator light Cooling on indicator light Temperature setting knob Operating switch with fan speed selection C - TEMPERATURE PROBE (BARE) - code 7050053 For RCC type remote control. possible uses: - change over probe (equipped with a tube retaining clip) for "-tube" appliances may operate in heating and cooling mode, - air temperature probe (to be placed on the air intake). Thermistance type CTN 3 kω at 5 C. IP 65 - protection class: cl. II. D - BOX-MOUNTED AIR TEMPERATURE PROBE - code 705005 For RCC remote controls. Enables the control unit to be placed outside the room to be air conditioned. Thermistance type CTN 3 kω at 5 C. The unit is mounted in a box similar to the remote control (IP 30 - protection class: cl. II - colour: white RAL 9003).
