WATTrouter ECO - user manual
outputs are used together with inserted SC-Gateway module. If this error occurs connect the control
circuits of all used SSRs to an external source.

Low tariff – if the low tariff signal is detected the red light comes on, otherwise is grayed.

Summer time - informs the user that the summer time mode is active. Summer time starts at 2:00 CET,
on the last Sunday in March and ends at 3:00 CEST, on the last Sunday in October. If the option "Use
summer time" is not marked on the "Other settings" tab, the indicator remains inactive.

CombiWATT is active – informs the user that CombiWATT mode is active. This indicator is active if the
condition necessary to run CombiWATT is valid, if the low tariff is active and if the CombiWATT
function has been configured for some output.

Output test is active – informs the user about a status when some of the outputs have been activated
by the TEST button.

SC-Gateway present – (since firmware version 1.7) informs the user about the presence of the SC-
Gateway module in the regulator.
Output statuses:

Load power - the assumed power drawn by the load connected to the relevant output. It refers to an
estimated power based on the output settings and may not correspond with the actual power output
of the load, as the power drawn by the connected load is not measured.

Supplied energy - daily energy counters measuring power already supplied to the relevant output. It
refers to an estimated energy supplied to the load, which is based on the output settings and may not
correspond with the actual amount of the power supplied to the load, as the power drawn by the
connected load is not measured. Energy counters inform CombiWATT mode or the corresponding
time schedule about the energy already delivered to the load and at the same time, they also inform
the user about the amount of delivered energy. Counters are reset to zero based on the configuration
of "CombiWATT - Energy counter reset"-field in the Other settings tab. WATTrouter device does not
know the status of the load and therefore, counters may also show much higher energy values than
those actually delivered to the load (for example, if the boiler is heated up during the day and turned
off by the thermostat).

Status output indicators - inform the user about the reason for switching, or possibly about the reason
for output restriction. There are 4 indicators:
a) Blue - it is displayed only if the output is switched on due to basic control process according
to the available surplus energy from PV-plant. This indicator also signals possible off-delay
time for the relay output (after being enforced by time schedule or CombiWATT mode).
b) Violet - it is displayed only if the output is switched on by the CombiWATT mode.
c) Green - it is displayed only if switching is enforced by time schedule.
d) Red - it is displayed if the output is restricted by time schedule.
Other statuses:

Configuration/object name - it is used to set label to the facility or the current configuration. Text may
contain maximum of 16 characters in ASCII encoding.

Sunrise today – it displays time of sunrise for today. This time is calculated directly in the regulator
based on the actual calendar date and the actual geographic location of the facility/building (see
"Geographic location" on the "Other settings" tab). The calculated time is converted to the current
local time based on configuration of the "Use summer time" and "Time zone" settings. The official
