For mixed radiator + UFH, set zone 5 to \u003cstrong\u003eRAD\u003c\/strong\u003e mode: that channel switches a radiator zone valve and calls the heat source without enabling the UFH pump or UFH valve outputs.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"background: #f0faf9; border: 1px solid #c8e6e3; border-radius: 6px; padding: 14px 18px; margin: 0 0 10px 0;\"\u003e\n\u003csummary style=\"font-weight: 600; color: #005c54; cursor: pointer; font-size: 15.5px;\"\u003eHow many actuators can I connect per zone?\u003c\/summary\u003e\n\u003cp style=\"margin: 12px 0 0 0; font-size: 14.5px; line-height: 1.6;\"\u003eUp to \u003cstrong\u003efour 230 V thermal actuators\u003c\/strong\u003e in parallel per zone output.
