TTH-6040-W Room Temperature Transmitter
Instruction manual
TTH-6040-W is a Modbus-based temperature sensor for wall mounting supplied with a junction box for conversion from 4-core cable to modular Modbus cable. TTH-6040- W is used to measure room temperature for use by ventilation systems.
PRODUCT PROGRAMME
| Type | Product |
|---|---|
| TTH-6040-W | Temperature sensor with Modbus for wall mounting |
CONTENTS
The box contains the following:
1 x Temperature sensor for wall mounting
1 x Junction box with modular connector
3 m QuickPlug™ cable
2 x Screws
1 x Adhesive pad 50×50 mm
FUNCTION
TTH-6040-W is a room temperature sensor with Modbus communication for use with
an air handling unit equipped with an OJ Air2 Master (rotary selector in
position 0). The sensor can also be used with other controllers that support
the Modbus protocol.
TTH-6040-W measures room temperature and communicates the result via Modbus.
The temperature sensor should be mounted on a flat surface at a representative
measuring point. Do not mount the sensor in direct sunlight or where draughts
occur. Connect the sensor to the junction box using a 4-core cable (not
supplied); see Figure 6. Connect the junction box to the OJ Air2 Master using
RJ12 cable. As long as the total cable length is less than 50 metres, no
special demands are made on cable type or shielding. The cable should be
connected to Modbus port A of the OJ Air2 Master.
MODBUS
TTH-6040-W uses Modbus RTU, 38400 baud, 1 start bit, 8 data bits, 2 stop bits
and no parity.

SERVICE AND MAINTENANCE
TTH-6040-W contains no components which require service or maintenance. The
ventilation holes in the temperature sensor must, however, be kept free of
dust and dirt so as to allow free and unrestricted passage.
Please contact your supplier if faults arise.
