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.
