Argo AR861-211 two zone issues.

I am new to this forum and new to heating issues. I have read most all of the postings on this unit but I would like a bit clearing up. To make sure I understand correctly. Have had no issues with this unit for over 15 years.

At start up this week. Neither thermostat turned on either pump to zone on or 2. I have checked all the relays. They seem fine. I have jumped a wire over both stat terminals and still nothing happens. Am I missing something else to test or do I need a new board?

Will attach photo asap.

Again. New to all this so may not understand all the lingo. Appreciate your time.

  • Do you have 110 volt power coming to the control?

    8.33 lbs./gal. x 60 min./hr. x 20°ΔT = 10,000 BTU's/hour

    Two btu per sq ft for degree difference for a slab

    A wire Jumping T1T1 should turn on zone one. Priority switch is on, so only zone 1 will activate while it has a call for heat.

    Jumping T1T1 does nothing.

  • The transformer may have blown or the circuit board is history. Time to replace it.
