Rationing system

8.1.2023

Dear customers, due to the high demand, we are introducing a rationing system for our most ordered products from 9 January 2023. For more information about this method of purchase, see here. New registrations are temporarily suspended until January 16, 2023 to allow priority purchase for our long-term business partners.

Design change

22.8.2022

Dear customers, due to better availability, from 22/08/2022 we deliver all our controllers in slightly different installation boxes, which are functionally completely identical to the original ones, only they are slightly different in design - they do not have the bottom sharp edge. The size of the controller, i.e. the number of modules and other parameters, does not change. The absence of the bottom sharp edge also objectively facilitates the installation of the controller in the switchboard.

End of cooperation with Russia

25.2.2022

Today we ended our cooperation with Russia. No orders from this country are possible and no technical support will be provided. Also, Russian language will be removed from all our future software updates.

Price increase

1.2.2022

Dear customers, business partners,
Due to the ever-increasing prices of all input components and energies, we are also forced to increase the prices of our products and accessories that we offer. Price increase 1.2.2022
As part of the adjustment of our price lists, on the other hand, there was a slight reduction in software extensions.
You can find the new prices in our e-shop.
Thank you for your understanding.

Global semiconductor shortages

18.10.2021

Dear customers, due to these shortages we are not able to produce many of our products, especially wattrouters. The problem might affect even our other products, please refer here for further info and expected lead times.

WATTrouter product line

How to choose the best model for me:

Check the value of main circuit breaker (or fuse) in your house. Select possible models according to the first row of the table below. The models WATTrouter M MAX or WATTrouter Mx 100A are ONLY suitable for main fusing element higher than 3x40A!
Depending on the required functionality and the monitoring and configuration options, select the controller model.

Parameter	WATTrouter ECO	WATTrouter M	WATTrouter Mx
Current limit (maximum value of main circuit breaker)²⁾	3x40 A	SSR-Type: 3x40 A MAX-Type: 3x125 A	Default type: 3x40 A 100A-Type: 3x125 A
Current measurement range²⁾	3x20 A	SSR-Type: 3x20 A MAX-Type: 3x100 A	Default Type: 3x20 A 100A-Type: 3x100 A
Number of outputs in 1 regulator¹⁾	6 2x relay 4x external SSR	6 2x triac 2x relay 2x external SSR	8 2x relay 6x external SSR

Notes:

It is possible to extend the number of outputs for ECO and Mx type by using the S-Connect protocol.
The current sensing module can be connected to external current transformers to increase current load and measurement range. For these purposes we do NOT recommend to choose WATTrouter M MAX or WATTrouter Mx 100A. When using standalone 100A CTs instead of the WT03/11 module, please note that they have maximum current 100A instead of 125A of WT03/11!
Functionality not guaranteed as there are many distributions / variants / updates for these operating systems.
PWM mode can be used even for suitable battery chargers, if they support external charging power control, eg. through 0-10VDC signal.
The function must be purchased as extra software feature.
Proportional control of immersion heaters and other heating elements ALWAYS needs an external solid state relay (SSR)!
Requires the SC-Gateway module and external wireless actuators.
We only provide documentation in Czech and English language. Documentation in other languages is available only as provided by our exclusive distributors. Due to increased maintenance reasons (especially for WATTrouter Mx) we won't provide user interface in other languages than given above.
