R4000 Temperature Controller with 1, 2, 4, 6, 8, 12* or 16* zones Heating/Cooling

R40x0 – more than just a multi-zone controller

Hardly any other product on market is as multifunctional as the R40x0: controller, digital indicator , graphical display and data logging in one product. With the R4010 expansion module you can expand the number of zones to 16. If you want to use a DIN rail variant, the R4020 offers the same function range. Operation and control takes place via the bus interface.

Quick to integrate, efficient to use

Where other controllers are becoming ever more complex and complicated to use, we are going the other way, without any loss of performance features. Everything you need is here, clearly displayed on a 3.5-inch touch screen. Its intuitive operation method lets you find your way around with no need for induction. No more poring over instruction manuals. Additional "signposts" when you first set up the system guide you through the well-structured operating levels.

Webservers from 2021

With our innovative web server and a network or WLAN connection, you can also parametrise and operate the controller remotely. This makes using the system easier than ever.

Save time – save money

Efficiency is almost everything. Save time setting the individual parameters. The copy parameters function lets you assign individual zones precisely. You save time here compared to individual settings and reduce the error quota.

Innovation in the area of compound heating

The multi-zone R4000 variants are "Green". Not green as in the colour but as in innovative energy-saving control functions. It used to be that with several different loops in the heating system, all heaters individually attempted to reach their setpoints as fast as possible. In the process, while some heating systems are working at full load for long periods, slower systems are still heating up. With the innovative new compound heating function, all controlled systems automatically adapt to the slowest zone, so that all heating systems reach the setpoint at the same time and with corresponding energy savings.
