TL;DR: simply add the command to execute after the "7," intro, e.g. 
"7,climatecontrol on".

The SendCommand API was built around the V2 message protocol, so you 
need to send commands as MP commands, see 
https://docs.openvehicles.com/en/latest/protocol_v2/commands.html for a 
list. MP command code 7 passes standard text (former SMS) commands to 
the shell, that's what the Wiki example shows (for V2 command "STAT?").

You can get the command response by listening to the CommandResult 
intent and reading the "cmd_data" extra. Be aware all command result 
will be sent as intents, so you need to check if a result matches your 
command (could possibly be improved if needed).
