7 Zones
This section will provide information in regards to messages that only apply to Zone commands.
This will include controlling the Zones as well as sending Request messages to "Get" the State of
the Zones. Zero-based values are used for the Zone Numbers (i.e. 0 = 1, 1 = 2, and 2 = 3 etc...)
7.1 ON/OFF
The simplest way to explicitly turn a Zone On or turn a Zone Off is by using the discrete Zone
On/Off Event. The Event Data fields determine the Zone and On/Off state. This example shows
using the Zone On/Off Event message to execute a Zone On command for Zone 1 of Controller
1. Refer to the Buttons section for information on toggling zone On/Off ("Power command
found under Keypad Events).
7.1.1 Set State
Turn a specific Zone ON or OFF using a discrete message.
Byte # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22
Value F0 cc 00 7F 00 00 70 05 02 02 00 00 F1 23 00 ## 00 zz 00 01 xx F7
cc = controller number -1
zz = zone number -1
xx = checksum
Byte #16 = 0x00 (off) or 0x01(on)
7.1.2 Get State
This is the Request message for the On/Off State of the selected Zone.
Byte # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
Value F0 cc 00 7F 00 00 70 01 04 02 00 zz 06 00 00 xx F7
cc = controller number -1
zz = zone number -1
xx = checksum
The return message would look like the following.
Byte # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
Value F0 00 00 70 cc 00 7F 00 00 04 02 00 zz 06 00 00 01 00 01 00 ## xx F7
cc = controller number -1
zz = zone number -1
xx = checksum
Byte #21 = 0x00 (off) or 0x01(on)
7.1.3 Set All Zones On/Off State
The RNET™ system can be sent a single message to issue an "All On" or "All Off" Event. The
Controllers have the ability to enable or disable the All On/All Off state control per zone. See
