Daikin MD5 - Relay Output Control

Relay Output Control
Using the eldbus for relay output control requires:
• Drive parameter values set as dened below.
• Fieldbus controller supplied reference word(s) in the
appropriate location. (The location is dened by the
Protocol Reference, which is protocol dependent.)
For example: To control relays 1 and 2 using serial
communication:
Set parameters 1401 RELAY OUTPUT 1 and 1402 RELAY
OUTPUT 1 = 35 (COMM).
Then, for example using N2:
• To turn Relay 1 On: Force object B07 to On.
• To turn Relay 2 On: Force object B08 to On.
• To turn both Relay 1 and 2 On: Force objects B07 and
B08 On.
NOTE: Relay status feedback occurs without conguration
as dened below.
