Switched Outputs - flamco Logotherm LogoTronic HIU Bedienungsanleitung

3.1 Switched outputs

Outputs R1 to R4 are switched via relays. The maximum switching load per output is 240 VAC, 2A.
Permissible actuators for connections R1 to R4 are:
• R1/R2: Wilo Yonos PARA ST pump **/7.0 iPWM2
• R1/R2: Grundfos UPM3 pump
• R3/R4: Lineg valve actuator EXT-LX90-F002
The MIX VALVE output is designed for 24 VDC with a maximum output of 13 W (550 mA).
Permissible actuators for the "MIX VALVE" connection are:
• Valve actuator LRG24A-SR
The connectors in the red rectangle are
intended for external cable connections
which may be required after installation of the
heat interface unit at the installation site.
All external connections are optional.
The heat interface units offer the basic
functions (hot water and heating) without
additional cabling.
The connectors are labelled on the cover plate. The sequence is, from left to right:
CON30: Battery
CON21: M-Bus
CON22: OpenTherm
CON23: External temperature sensor
CON24: Room thermostat for heating/
cooling
CON25: Room thermostat for heating
CON26: Hot water circulation
CON27: Room thermostat for cooling
CON28: Pre-payment unit
CON29: RS485 bus connector
Note: The pin order of the connections does NOT correspond to the pin assignment of the board
schematics!
