Base setup E2 FunctionThe second signal input is not activated at the factory for modes with one sensor.The function is automatically jointly programmed in operating modes using two sen-sors. The second analog input is thus allocated and additional function allocations arenot possible.• 2.04 E2 Function at |4E| preprogrammed = comparison value with control tohigher temperature. Alternative: average of 2 measuring points for this must bereprogrammed on function |3E| preprogrammed sensor type “TF”.• 2.05 E2 Function at |5E| preprogrammed = regulation on difference temperaturebetween sensor 1 and sensor 2. Preprogrammed sensor type “TF”.Adjustable “E2 Function”• |1E| = External Setpoint e.g. via external signal (0 - 10 V) instead of “Setpoint 1”– For sensor type “E1 Analog In” = “TF or PT1000”: 0 - 10 V -50.0...+150 °C.– For sensors with active signal: 0 - 10 V 0 - 100 % sensor measuring range.• |2E| = External manual operation via external signal (0 - 10 V). Switch overbetween settings on the device and external manual operation via digital input (IO Setup: function |7D|).• |6E| = sensor for outdoor temperature-dependent setpoint adaptation (at 2.03 notpossible), pre-programmed sensor type “TF..”.– additional parameters menu group “Setting”: T-Band, T-Start SA, Min. Setpoint.– additional parameters menu group“Info”: Setpoint Control– Example Setting for operation 4.01 ... 4.03 / additional menu items.• |7E| = Measurement value = Measurement value e.g. for limit indication, display inInfo menu “E2 Actual”.• |8E|... |13E| = sensor input for control circuit 2 (at 2.03 not possible) basesetup / operation with second control circuit.OFFE2 Function9.2.2 Settings for operation modes 2.01 ... 2.052.01 Temperature control airconditioning and refrigeration(preset set-point 20.0 °C, P-band 5.0 K)2.02 Temperature control depending on outdoor temperature(preset set-point 5.0 °C, - P-band 20.0 K)2.03 Temperature control with pre-programmed additional functions (heating, shutter, temperature monitor-ing).2.04 Temperature control with 2 sensorsComparison with control to higher value “E2 Function” set to comparison |4E|. Display duringoperation: “Control value ”Alternative: Average calculation of 2 measuring places “E2 Function” set to |3E|. Display duringoperation: “Average E1 / E2 ”2.05 Temperature control with 2 sensors, regulation on difference temperature.Display during operation: “Value of E1 - E2” in K, “E1” = reference temperatur, “E2” causes positiv (E2< E1) or negative (E2 >E 1) difference.Main menu SettingSettingProtocolBase setupController SetupIO SetupSetting Setpoint1Setting range with passive sensor type “TF”, “PT1000”: -50.0...150.0 °CFactory setting: 2.01 , 2.03 , 2.04 : 20.0 °Cat 2.02 : 5.0 °Cat 2.05 : 0.0 °CSetting range with passive sensor type “MTG-120V”: -10.0 °C...+120.0 °CFactory setting 2.01 - 2.05 : 55.0 °C20.0 °CSetpoint1Operating Instructions Fcontrol – model series FXDM25/32AM ProgrammingL-BAL-E212-GB 1451 Index 003 Part.-No.35/123
