Condensation pump
The condensation pump output, 230VAC,1A, will work together with the “Cool”
output.
Swing
The swing output, dry contact, can be activated using the remote control, and will
remain ON until turned OFF using the remote control.
When ON, the swing output will work only together with the fan, and will turn OFF
when the fan is OFF.
Jumper JP1 – Auto fan configuration
SHORT - In cool and heat modes – fan works on demand (auto fan)
- Suitable for No-valve systems (unit runs on fan without valves)
OPEN - In cool mode – fan works continuously.
- In heat mode – fan works on demand (auto fan)
Jumper JP2 – 2-Pipe / 4-Pipe
OPEN - 2-Pipe configuration (one valve).
- “Cool” output connected to the valve (cooling and heating).
- No Auto change-over mode
SHORT - 4-Pipe configuration (two valves)
- “Cool” output connected to cool valve.
- “Heat” output connected to heat valve.
T2 logic – Mode selection in 2-Pipe system
T2 Connected:
- System mode defined by T2 sensor as follows:
T2 < 20°C COOL
T2 > 20°C HEAT
- Mode is NOT selectable by occupant.
T2 NOT Connected:
- Mode selected by occupant.
T3 logic – Fan operation in heat mode
T3 < 27°C Fan OFF (preventing cold drafts)
T3 > 32°C Fan ON
T4 logic – Fault input
- Voltage free, normally close input.
- When open, the unit will turn OFF and LEDS in M101P will flash.
