BT08L005GB-01[Pa]PACKAGED362 - 9043WVM - MODULATING 3-WAY VALVETo be used in conjunction with the hot water coil (optional). It is controlled by the on-board microprocessor by meansof a 0-10V signal and allows fully automatic adjustment of the hot water coil. The valve with modulating actuatoris provided already installed and wired on the machine.PRESSURE DROP MODULATING THREE-WAY VALVEQ [l/s] = water flow rateCHW2 - TWO-ROW HOT WATER COILOption recommended for very cold climates since it allows heating of the served room. The battery is equippedwith a thermostat for the anti-freeze function. The anti-freeze function is always active, even when the unit is instandby. If necessary, it forces opening of the valve to the maximum allowable value for allow passage of water inthe coil and to prevent the formation of ice.In heat pump mode, the hot water coil may allow both pre-heating of the inlet air to the main coil, as well asintegration of the capacity provided by the heat pump. As an alternative, it may intervene in complete substitutionof the thermal capacity provided by the compressors. This is possible by setting a turning point, i.e. a temperaturelimit of the fresh air below which use of the compressors is blocked, and the water coil is used as the soleresource. If the water coil provides pre-heating of the air, the control logic reduces its power to a preset value,which keeps the compressors from working with condensation temperatures that are too high. If instead the watercoil is used as the main resource (e.g. because the compressors are not available), the maximum power will beprovided.HOT WATER COIL PRESSURE DROP: AIR SIDE6560464-704 804-90455504540353025362-452THE AIR SIDE PRESSURE DROPS ARE RELATI-VE TO THE MEDIUM AIR TEMPERATURE OF20°C AND ARE TO BE ADDED TO THE PRES-SURE DROPS DUE TO DUCTS, TERMINALDEVICES AND ANY OTHER COMPONENT THATCAUSES A DROP IN WORKING DISCHARGEHEAD.20154000 5000 6000 7000 8000 9000 10000 11000 12000 13000 14000 15000 16000Q [l/s]HOT WATER COIL PRESSURE DROP: WATER SIDEPRESSURE DROPS ON THE WATER SIDE ARECALCULATED CONSIDERING AN AVERAGEWATER TEMPERATURE OF 65°CQ[L/S]= WATER-FLOW RATEThis option reduces the available static pressure (air side).36The component requires connection to the hot water plumbing system (to be provided for by the client).
