It is engineered for use with pre EXP-4 models, as EXP-4 units have equivalent functionality built in. HVAC technicians and hydronic heating specialists install this card to reduce seasonal start-up failures caused by harsh water conditions. The control can also be configured to cycle more frequently during cold weather months, lowering the risk of freeze-ups in hydronic systems.\u003c\/p\u003e\n\u003cp\u003eThis plug-in card is suited for residential and light commercial hydronic heating systems where pump and zone valve activity must be maintained during periods of low demand. It is particularly useful in systems that use domestic hot water heaters as a heat source, where systematic water circulation helps minimize bacterial growth. The card attaches directly to the Expandable Control, making it a straightforward addition during routine service or seasonal commissioning.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid-state universal timer design for reliable, long-term operation\u003c\/li\u003e\n  \u003cli\u003eCycles all connected pumps or opens all zone valves at selected intervals\u003c\/li\u003e\n  \u003cli\u003eConfigurable cycling frequency to reduce freeze-up risk in cold weather\u003c\/li\u003e\n  \u003cli\u003eHelps minimize bacterial growth in systems using domestic hot water heaters as heat source\u003c\/li\u003e\n  \u003cli\u003eReduces seasonal start-up problems associated with harsh water conditions\u003c\/li\u003e\n  \u003cli\u003ePlug-in card format for direct installation into compatible Expandable Controls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with pre EXP-4 Expandable Control models.

Power down the Expandable Control and the associated hydronic system before inserting or removing the plug-in card. Verify the control model is a pre EXP-4 unit before installation, as EXP-4 models do not require this card.
