Page 3: Introduction
Through the local bus port it is possible to connect up to 4 different devices with other devices of the same W digital series with the purpose to share the sensor and the operating mode. The local bus also allows the W500H to be supervised if at least one W500TMB or W500HMB is connected. -
Page 4: User Interface
USER INTERFACE The device is characterized by a user interface composed of a 3 ½-digit FND display, five keys and twelve LEDs located on the front membrane. The information displayed on screen depends on whether the sensors are present or not and on the related function enable. -

Page 8: For The Digital Relay Output 2 It Is Possible To Select
FOR THE DIGITAL RELAY OUTPUT 2 IT IS POSSIBLE TO SELECT: MODE D1: ON/OFF HUMIDIFICATION HYSTERESIS If the output value must turn to ON when the value of H Humidity Sensor drops under (SPH) operating humidity set value minus (BPH) hysteresis band. When the set point is achieved the relay output is OFF. -
Page 9: Control Type
CONTROL TYPE Once the OPERATING MODE is stated, it is necessary to set the CONTROL TYPE, i.e. the control criteria used by the OPERATING MODE. The control type can be: - Proportional or Proportional + Integral (P or P+I) - With fixed operation set point or compensated in function of Compensation Sensor. - With or without minimum and/or maximum limit in function of Limit Sensor. -
Page 10: Set-Point Compensation
SET-POINT COMPENSATION The operation SET-POINT can be fixed or determined by a compensation slope according to the value given by the compensation sensor. Both A1 and D1 temperature loops can be temperature compensated (the SC sensor is necessary) or humidity compensated (SH sensor). -
Page 11: Min/Max Humidity Limits On A1 And D1 Loops
MIN/MAX HUMIDITY LIMITS ON A1 AND D1 LOOPS Limit loops are optionally active in A1 and D1 loops only; they are P-type and always operate with fixed set-point. If enabled, they work in parallel to the control loop. For each operating mode (except Mode D4) both minimum and maximum limits can be enabled separately. -
Page 12: Operating Modes
OPERATING MODES The equipment is able to operate according to three different operating modes, which are: 0) Comfort – all loops are ON during control (including the Limit Loops). 1) Reduced – the Control Loops operate on a reduced Set point. The Limit Loops remain ON with their set point. -
Page 13: Clock Enable With Time Schedule
CLOCK ENABLE WITH TIME SCHEDULE If the W500 is RTC-provided or it is connected via LinkBus to a device with clock, it is possible to define the Operating Mode according to a weekly schedule and a daily schedule. The clock enable of each Control Loop is obtained by setting the parameter ABO = On. -
Page 14: Storing Data In Permanent Memory
4 controllers can operate according to the same time schedule. The equipment without the RS485 serial communication port (W500T or W500H) can be supervised if connected via LinkBus to at least one equipment with RS485 (W500TMB or W500HMB), setting it as Master i d L (i.e. -
Page 15: Enthalpy Comparison With Outdoor Humidity Sensor From Another W500H
When the function Enthalpy Comparison is active (mode A3 for analogue output 2 and/or D3 for relay output 2) it is possible to utilize SH signal from another W500H as outdoor humidity sensor. In this case we achieve a complete Enthalpy comparison of temperature and humidity using the outdoor humidity value sent through the LinkBus by another W500H. -
Page 16: Modbus Communication
MODBUS COMMUNICATION Through the ModBus protocol it is possible to supervise up to 255 groups of 4 equipments, for a total of 1020 devices. The ModBus connection is carried out on the equipment with IDL = 1 (Master) through the RS485 serial port. The values managed by supervision and those managed by the controller menu are the same. -
