8-Zone 120 V Wired Valve Relay Control

The SALUS AKL08 Wired 8-Zone Valve Relay Controller accepts inputs from up to 8 wired thermostats to control up to 8 zones of radiant heating (32 zone actuators or 8 zone valves). Voltage-free connections are available to provide boiler heat demand and system pump operation. Dry-contact inputs allow for dew-point sensing and heat/cool changeover. Jumpers to set boiler off delay or NC/NO valve actuators. The AKL08 will control hydronic zones to efficiently heat homes, offices, or other occupied spaces. -  2-, 3-, or 4-wire connected thermostats.  8 zones –4 actuators or 1 zone valve per zone (total load 3.3 Amps).  Select normally open or normally closed zone valves.  Dry contact inputs for dewpoint sensing and heat/cool changeover.  Dry contact outputs for boiler or circulator pump control.  Pump ON/OFF delay or 3 minutes (fixed).  Boiler ON delay 3 minutes (fixed), OFF delay jumper selectable 0 or 15 minutes.  USB Port for AC10RF Coordinator (sold separately) for stand-alone networking
