Installation
Suitable for installation on valves of radiators, floor heaters etc.
For correct measurement of room temperature, horizontal installation of the CORA-HKT is recom
-
mended.
In relation to power supply and data transmission, 3 options are available.
1.
Battery
powered,
wireless
data transmission
2.
12V
wired power supply,
wireless
data transmission
3.
12V
wired power supply,
wired
data transmission via
CORA-DL
The thermostat can only be operated using one of these options. It can also only be connected/cou
-
pled with a single controller at a time.
When programming on a controller using the CORA-HKT, it is necessary to enter whether wired or
wireless data transmission is in use.
When using wired
12V
power supply, values are updated every minute. When
battery powered,
val
-
ues are updated every 5 minutes.
If the CORA-HKT is powered using batteries, it cannot be used as a HOP node (see „Relaying wireless
signals“).
Wireless system
Principles
The wireless system comprises multiple CORA devices (e.g. CAN-MTx2 and CORA-HKT), which com
-
municate with one another, exchange data or transfer firmware.
The wireless range is around 1000 m outdoors, and typically 30 m in buildings (through approx.
2 walls/ceilings, depending on thickness and material). Up to 3 additional wireless devices can be
used as a bridge to enable data to be exchanged under deviating conditions.
RCV-DL, GBS-F and RAS-F devices
cannot
be used.
Pairing CORA devices
Two steps are carried out to pair two devices:
1. Allow
pairing on the
target device
2. Initiate
pairing on the
control device
To allow pairing on the EHS-R (= target device), double click on the button on the casing (= 2 click
within 2 seconds). Pairing is then allowed for 5 minutes (see chapter "Reset / Pairing").
On the control device, the CORA ID for the CORA-HKT is required for pairing.
The pairing process on other devices (control device) can be found in the corresponding operating
instructions.
Relaying wireless signals
Wireless-capable devices can relay signals of other devices. All required settings for this are carried
out at the device, which transmits the signal to be relayed.
The CORA-HKT can also be used to relay wireless signals of other devices, but only when used with
wired power supply. Should it receive signals for relaying, it does so automatically. No additional set
-
tings for the CORA-HKT are necessary for relaying signals.
