4. If using the HE-HT01 for radiant floor heating, connect the NTC temperature sensor
wire to the terminals labeled “NTC.” A 10 kΩ NTC sensor is included inside the HE
-
HT01 packaging, but any NTC sensor can be used.
Note:
If an NTC sensor other than 10 k
Ω
is used, sensor Parameter value should be
changed in the settings menu (Parameter 10
–
FSr)
–
see “Settings Menu” section
below.
5. If you will be using an external device to select modes for the HE-HT01 (such as a
security system), connect wires from the ex
ternal device’s dry contacts
according to
connection diagrams 1 (or 2 or 3 or 4).
Note
: There could be “EXT” label instead of “S1”, ”Sx”.
6. Making sure the HE-
HT01 backplate is oriented on the wall with the word “TOP”
pointed upwards, secure the backplate onto the electrical junction box using the four
provided screws (do not overtighten). Once the backplate is secured onto the wall,
assemble the HE-HT01 display unit onto the backplate by first carefully aligning the
two top snap connectors, and then gently p
ushing the entire display unit until it ‘snaps’
into position all the way around.
7. Next, switch On the main power at the circuit breaker (see photo above). The HE-HT01 will start up showing the
original default factory settings.
8. Remove the clear protective film from the display unit and frame by pulling on the top right-hand orange color tabs.
Disassembly
1. To disassemble, ENSURE POWER IS SWITCHED OFF at the main circuit breaker AND THE LCD SCREEN IS
BLANK.
2. To remove the HE-HT01 display unit grasp firmly at the bottom and pull backwards while tilting outwards until all
tabs disconnect.
3. Remove screws from backplate and disconnect the wires by inserting a small Phillips-head screwdriver into the slot
beneath each wire to release.
