THS04 wall thermostat
RT-SVU010A-GB

Wiring
Bus
Communication between CH536 and THS04 is done by Modbus on RS485.
On CH536 a bus is dedicated to that communication: J9 FBus1
This is based on three wires: plus ; minus ; reference (circle)
Vout is not used. (cf fig.1)
On THS04, those three signals are: Rx+/Tx+ ; Rx-/Tx-; GND (cf fig.2)
Power supply
In addition to communication signals, THS04 requires power supply.
X201 to be connected to GND of THS04
X200 to be connected to 24V~ of THS04

Menu Navigation
Navigation principle
Navigation through menus is done by the “push&rotate” button.
The way to use that button is: rotate to modify a setpoint or a value, then wait 3s for that setpoint or
value to be automatically registered. The symbol “Set” disappears.
That important way to use it is symbolized with:
