Additional options for external connections through the X5 terminal block are provided:
• connecting a contact of the automatic fire extinguishing system (inscription on the label - «PK1»)
• connecting a humidity sensor contact - humidistat (inscription on the label - «H1»)
• connecting a three-position air damper (inscription on the label - «1», «2», «3»).
When connecting the contact of the automatic fire extinguishing system, remove the jumper between the X5:1 and X5:2 terminals of the
X5 terminal block. In this case, a normally closed «dry contact» is used, which when triggered in case of fire, opens the unit control circuit
from the fire alarm panel and de-energizes it.
The humidistat is connected to the X5:3 and X5:4 terminals of the X5 terminal block. Normally open «dry contact» is used. When it is
closed, the unit switches to maximum speed.
The air damper actuator is connected to the X5:5, X5:6, and X5:7 terminals; «M» (1) contact of the damper actuator – to the X5:5 terminal
(inscription on the sticker «1»); «L» (2) contact – to the X5:6 terminal (inscription «2»); «L» (3) contact – to the Х5:7 terminal (inscription «3»).
The recommended type of damper is KRA (for round or rectangular air ducts) with an LM 230 A actuator (Belimo).
