*)
The outdoor temperature sensor can be connected to either the controller or to a thermostat.
**)
Connect either COLD or PUMP P2 (secondary heating/cooling circuit) to the connection terminal.
***) Select one of the inputs (heating/cooling switch, pump control signal, or immersion thermostat) and set parameter 11 – Wired Input 1 selection, or parameter 12 – Wired Input 2 Selection, accordingly. The heating/cooling option can only be used in systems without a registered wireless thermostat. ****) Optional temperature limiter connection, fitted with a cable bridgre from the factory. Remove the bridge if a temperature limiter is to be used together with PUMP P1.
LT
*****) Optional return sensor. Can only be used in systems without a registered wireless thermostat.
