FREQUENTLY ASKED QUESTIONS
Where should I locate my WH1?
WH1 should be installed out of direct sunlight and at least 1 metre from other electrical equipment such as
radios, TV, Wifi routers, PCs etc. Place it in a central part of your building where it can easily be accessed and
viewed by those who need to set and maintain it.
Where should I locate my R1?
The R1 acts as the temperature sensor for the heater(s) under its control. It should be placed close enough to
the heaters to minimise unsightly wiring whilst far enough away to sense air temperature required for the zone.
Before finalising your location, ensure you can establish good communication between the R1 and WH1.
What is the “Window Open Function”?
For rooms above 14°C, if the temperature drops by 2 degrees or more within a 15 minute period, the R1 will
shut off the heaters under its control for an hour, unless a subsequent command is issued.
The “Power” LED on
the R1 will turn Red. The R1 icon on the WH1 will also display an orange Alert diamond
.
This is to avoid wasting electricity when a window or door has been left open and is in line with new European
EcoDesign Legislation for Electric Heating.
What if an R1 is off-line?
If an R1 loses communication with the WH1, then no temperature or Mode information is visible on the R1 icon
in the Manage Zone page. If you click on the R1, you will see a “Device offline” message in the header of the
Manage Zone page.
Check the R1 has not been switched off at the mains.
If the R1 was previously in communication, check it has not been moved, or obstacles placed in its way that may
be blocking the signal (Television, large metal surface, microwave oven, proximity to Wifi Router). The R1 may
also just be at the limits of effective communication range (walls, metal obstacles like immersion heaters).
When an R1 is brought back online, it may take several minutes for the WH1 to detect it and show its status on
the Manage Zones screen.
What happens
if there’s a power cut?
If there’s a power cut, your system will restart with its previously stored settings and mode for each R1. R1s that
were
switched “off” by the WH1 before the power cut will resume functioning with the
frost settings
and will
have to be turned “on” again as normal to resume normal function. Under schedule mode the next programme
cycle will establish the correct setpoint temperature.
Can I control the R1 if the WH1 is off-line?
Yes. If the WH1 is offline for whatever reason, the R1 will continue to perform its last-received command. The
R1 possesses an on/off power button and a one hour “boost” function which will work independently of the
WH1, even if the WH1 screen shows the system itself is “off”.
There is a Red LED Light on
“Power” on my R1
and the heater isn’t on
. What does this mean?
It means “Window Open” mode has been triggered by the R1. This mode remains triggered for an hour unless a
new command is received from the controller or the “boost” or power buttons pressed
on the R1 itself.
Can I use an R1 in a bathroom?
An R1 can only be used in a bathroom if it is outside Zones 0, 1 and 2.
It must be positioned more than 60cm away from any source of running or splashing water and cannot be
installed where there is a risk of water contact. It must not be possible for anyone in the bath or shower to be
able to reach out and touch the R1.
Herschel Infrared Ltd cannot accept responsibility for damage, loss or injury caused by ingress of water or
moisture into the R1 unit.
