WATTrouter Mx - user manual
Note: It is allowed to connect only pure resistive loads to power SSRs. These loads cannot be fitted with own
electronic control system nor with built-in motors (e.g. fans - see the note below). These loads may only have
regular mechanically controlled thermostats and indication LEDs or neon lamps. Almost any regularly produced
boilers, immersion heaters, infra radiators, heating floor pads, motor-free dryers (infra dryer), oil heaters,
cartridge heaters in a solar tanks, etc. may be used.
Note: Each SSR output is capable of providing power to heating loads with built-in fan for longer time (such as
hair dryer, heat radiator). These loads are fitted with a built-in thermal protection, which, if synchronous SSR
control mode is used for that load, will disconnect the load for low power of SSR output (in this scenario, the
built-in fan's power is not sufficient to cool down the heating element of the load). Therefore, consider fitting
these loads to SSR outputs carefully.
Note: Heating loads connected via residual-current circuit breaker may be connected to SSR outputs.
Note: Heating loads with nominal power up to 2 kW may be connected to relay outputs directly, without using
external contactor.
Carefully examine connection of the controller and then turn off all circuit breakers and deactivate fuse
switches for connected loads. Then turn on the main circuit breaker and the regulator circuit breaker (L1 power
supply). The LED PWR lights up (power on indication). If the light is off, or if it does not shine permanently, or if
the LED ERR starts to flash (error status), proceed according to instructions specified in the Troubleshooting
chapter. In default status no output is active and therefore, no load will be turned on.
Now the controller is fitted and ready for configuration.
