// SG-Ready adapter for heat pumps controlled via two relay contacts.
|
|
//
|
|
// SG-Ready uses 2 binary relay contacts to select operating mode:
|
|
// SG1 (blocked): relay1=OFF, relay2=OFF — forced off
|
|
// SG2 (normal): relay1=OFF, relay2=ON — normal operation
|
|
// SG3 (surplus): relay1=ON, relay2=OFF — raise setpoint (surplus mode)
|
|
// SG4 (boost): relay1=ON, relay2=ON — forced max heat
|
|
//
|
|
// Power mapping:
|
|
// applyPower(0) → SG1 (blocked)
|
|
// applyPower(<normalPowerW) → SG2 (normal)
|
|
// applyPower(normalPowerW) → SG3 (surplus)
|
|
// applyPower(>normalPowerW) → SG4 (boost)
