Herschel iQ T1 User manual

T1 Wireless Thermostat
WIRELESS
THERMOSTAT
The Herschel iQ T1 Thermostat is a modern control
specifically designed to regulate Herschel Infrared
Heaters when paired with the iQ R1 wireless receiver.
When used in conjunction with the iQ HUB, it can also be
controlled remotely via the internet using an app.
T1 features 3 manual modes and 7 x 1 day
programming. T1 will operate your Herschel heater(s) by
turning them ON if the room temperature is lower than
the desired temperature and will turn them OFF once the
desired temperature is reached or exceeded.
The T1 is designed to be easy to operate and
incorporates the latest energy-saving features including
Herschel’s open window technology and an adaptive
start function ensuring your room is always at the right
temperature with the least energy use.
The T1 can be paired to more than one R1 wireless
receiver, meaning multiple heaters within the room can
be controlled by the T1 Thermostat. Multiple heaters can
also be wired to a single R1 receiver so long as 10 amps
is never exceeded per R1.
Please read these instructions in conjunction with the R1
Wireless Receiver instructions. Both devices T1 and R1
must be “paired” to each other for the T1 to operate.
NOTE: The T1 cannot control Herschel infrared panel
heaters without the R1 Wireless Receiver.

the right day.
Mode temperature settings
The T1 has 3 temperature modes. Use these modes if
the 7 day schedule is not required, or to override the
schedule –for example select “Comfort” if you are at
home all day, or “Energy Saving” to economise on
heat, or “Away” when you are on holiday.
The comfort mode is displayed as a symbol (e.g.
25.5°C).
The energy-saving mode is displayed as a symbol
(e. g. 20.5°C).
The holiday mode is displayed as a symbol (e.g.
10°C).
To set Mode temperature:
•Press the MENU button, the Comfort Mode
temperature symbol will be displayed.
Change the temperature using the Up and Down
buttons. “SET” is displayed indicating you have
changed the setting.
•Press MENU again to display the Energy Saving
mode temperature . Change the temperature
using the Up and Down buttons. “SET” is
displayed indicating you have changed the setting.
•Press MENU again to display the Holiday (Away)
Mode temperature . Change the temperature
using the Up and Down buttons. “SET” is
displayed indicating you have changed the setting.
•Return to the main page by pressing the Return
button.
To select a mode at any time, press the MENU button.
This selection will override the schedule or current
temperature setpoint. For example by selecting
Holiday mode (using the MENU button) the T1 will
maintain your holiday temperature setting until
another mode is selected.

T1 (Gen 3) WIRELESS THERMOSTAT
Program Mode
The T1 has a 7 x 1 day timer (Monday to Sunday) with
4 periods per day. Set Period 1 as the temperature
for the morning. Period 2 is the fallback temperature
for the daytime. Period 3 is the temperature required
for the evening and period 4 is the overnight
temperature.
Unlike conventional heating, Herschel Far infrared
directly heats the room (the “Thermal Mass”). For
areas in frequent use it is more economical to avoid
temperatures dropping too low as the heater will need
to be on for a much longer period to restore
temperatures. We recommend overnight setback
temperatures of no lower than 14°C and daytime
temperatures of 16°C and above.
To select Program Mode press MENU until PRG is
displayed as the mode. The schedule will then operate
until another mode is selected.
To set the 7 days program
The default program you will receive with your T1 is:
To alter this schedule:
•Press the PRG button for 3 seconds to start the 7
x 1 day program setting. The First period of the
First day is selected.
All days
Period 1
0600 20℃
Period 2
0900 16℃
Period 3
16:00 20℃
Period 4
23:00 16℃
•Press the Up or Down button to change the time of
the first period of the day’s program.
•Press PRG again to move to the temperature
setting of the first period and use the Up and Down
buttons to adjust the temperature.
•Press PRG again to move to the second period of
the first day’s program. Repeat the above
procedure to finish setting the other periods of the
first day’s program.
•Press PRG again to move to the first period of the
second day.
•Once setup is complete, press Return to get back
to the main display.
Temperature can always be overridden manually by
pressing the Up and Down buttons. The temperature
will remain at this setting until the next programmed
change occurs. For example, using the default
schedule in the previous table, if it was 18:00 on a
Monday the thermostat would be set to 20°C. If you
wished to increase the temperature to 21°C, press the
Up button to increase temperature to 21°C. The
thermostat would then retain this setting until 23:00
when the period 4 schedule would reduce the set
temperature to 16°C.
Parameter Settings
The T1 has several special operating parameters you
can set, these are:
Temperature Calibration to adjust the unit to
compensate temperature up or down by up to 8°C. For
example if you have another control in the room which

T1 (Gen 3) WIRELESS THERMOSTAT
reads differently from the T1, or if you have to place
the T1 close to the radiator and don’t want to have the
T1 stop the heat before the rest of the room has
warmed up (negative adjustment needed). Or perhaps
the T1 is placed in a cold area (e.g by a window) and
you want the T1 to stay on less so the rest of the room
does not overheat (positive adjustment needed).
Open Window on / off
Open Window is an energy saving feature. When the
room temperature is 14°C and above, if the thermostat
senses a fall in temperature of 2°C or more within a 15
minute period, the T1 will turn off the heater(s) for one
hour and “OP” will show in the display. This is to avoid
wasting electricity where a window or door is likely to
have been opened. Whilst you can always override
this by adjusting the temperature Up or Down or
pressing the BOOST button on the R1, you can also
switch off the function totally (see how to change the
Parameter Settings below).
Adaptive Start
Adaptive Start is another energy saving feature
designed to smooth-out heating consumption when
large jumps in temperature exist between the current
set temperature and the next scheduled temperature
(implies large energy use). Herschel’s adaptive start
function will compare the currently sensed
temperature against the next scheduled setpoint and if
the difference is more than 5°C it will start the heater
earlier. You can use Parameter Settings to turn off
Adaptive start totally.
How change Parameter Settings:
•Turn off the T1.
•Press MENU and UP button together for 3
seconds. This brings up each available parameter
in turn as shown in the table below. The parameter
is changed by pressing the Up or Down button and
the next parameter selected by pressing MENU.
Failsafe Mode
If the T1 is paired to the iQ Hub and fails to receive any
commands for more than 30 minutes, the T1 will
operate on its current settings until a new command is
received.
If the T1 loses signal with the R1 for more than 30
minutes, the R1 will default to 18°C.
This feature ensures that heaters can still operate
sensibly and safely in case of failure or signal issues
with the hub or T1.
