4.4 Relay outputs
External devices or systems can be controlled with relay
control outputs (+ 24 VDC). The units two inputs (IO1
and IO2) can control external relays. SEM* module has
one inbuilt relay (IO3) and two outputs for external relays
(IO4 and IO5). IO5 is grounding digital output for direct
connection to automation system.
Installation
Install external relay or system according to drawings.
NOTE! The control card can be damaged if you short-
circuit the IO connection selected by the relay output.
Settings

trols/AO4 menu.
Operations
Select required output function:
1. Operating mode
Operating mode output 0...10 VDC
0 V = NA
1 V = Travelling
2 V = Away
5 V = Home
8 V = Boost
10 V = Stopped
2. Operating mode, stepless
Operating mode output 0...10 VDC
0 V = Control disabled
1 V = Travelling
2 V = Away
Stepless output between Away and Home
5 V = Home
Stepless output between Home and Boost
8 V = Boost
10 V = Stopped
3. Temperature setpoint
Temperature setpoint (10-30 °C) corresponds to 0...10 V.
4. Modbus
Output is controlled with Modbus.
4.6 Smart Access
Unit can be controlled, monitored and commissioned
with web service Smart Access*. Smart Access allows
automatic alarm and service notifications through email.
Smart Access provides unit specified links to spare parts
and filter web shop and to Casahelp.
