io mux

Overview and configuration of input/output ports IO mux

1. Select input/output type
On the left side there are defined MC controller (MC-230) ports to which could be assigned MC-230 functions (digital, linker reset, router reset, etc).
Default settings are for e.g. QX0 → digital 1 while digital 1 is defined for consumer 1 (settings page). It could be changed in a way to define new function role to QX0 port e.g. for linker reset
If it is selected Enable consumer at input IX0,IX1 or IX2 it means that dedicated consumer will be managed (ON/OFF) by input signal on IX0,IX1 or IX2. For example, thermostat signal is wired to IXO port and via IO mux defined “Enable consumer 1” to IX0. While thermostat is active, it is consumer 1 active as well and vice versa.
Limitations: one temperature sensor is allowed, one consumer could be managed by one input only
2. out mode
Managed consumer input/output mode (normal or inverted)


1. System settings
[ autodetect ] Click to find HEMS in local network
eStore c….. eStore serial number (automatically detected or can be entered manually).
[] enable When checked HEMS will read Grid, first plant and first Storage directly from eStore (so there is no need to duplicate power-sensor).
[detect] eStore address is cleared and new eStore can be detected.
HIQ Home c….. HIQ Home serial number (automatically detected or can be entered manually).
[] enable When checked HEMS will read Grid power and energy from HIQ Home (so there is no need to duplicate power-sensor).
[detect] HIQ Home address is cleared so new can be detected.
Virtual grid PS [] enable Check if system is without main grid power meter. Energy, power and currents are calculated from other power meters.
