Overview
The RBW304-C is a wall-mounted room operating unit with an integrated digital temperature sensor, a backlit display and a setpoint knob with confirmation key. This model adds fan control buttons. The display shows presence, fan status, heating or cooling, window contact, weekly schedule, time, date and project-specific messages. It connects over a 4-wire terminal or RJ9 socket to the CAN field bus and is powered at 12 V DC. It can be connected to the DDC420 (up to 3 units), to DDC4000 and DDC4000e stations (up to nine units on addresses 1 to 9), and to RCN room controllers (up to four). It screws onto a standard flush box, and the Z146 adapter frame allows direct wall mounting.
