If your Amtrol Water Heater's Smart Control™ is displaying an ER1 message, it could indicate: * The temperature sensor is unplugged. Ensure the sensor is plugged into the Smart Control™ receptacle. * The temperature sensor is damaged or faulty. Replace the sensor wire (thermistor). * There is water in the therm-well. Replace the therm-well.
What to do if Amtrol BoilerMate RTR Water Heater water is too hot and/ or shows ER2 message?
If the water from your Amtrol Water Heater is too hot, or you're seeing an ER2 message on the Smart Control™, consider these possibilities: * The plumbing might be incorrect. If the Boiler Return is connected to the suction side of a heating circulator, overheating can occur when the home's heat is on. Correct the plumbing. * The temperature setting could be too high. Reduce the temperature setpoint. * The temperature sensor may not be fully inserted. Re-insert the thermistor wire or temperature sensor. * A zone valve might be stuck. Repair or replace it. * The flow check valve could be stuck open. Clean, repair, or replace it.
Why is my Amtrol BoilerMate® Water Heater making noise?
If your Amtrol BoilerMate® is making noise, it could be due to several reasons: * There might be air trapped in the boiler loop. Purge the boiler loop and inspect the air elimination equipment. * The circulator pump could be faulty. Repair or replace the pump. * Thermal expansion can cause noise. Make sure the correct Therm-X-Trol® or equivalent thermal expansion tank is installed and adjusted properly. * During the initial fill, some noise is normal. When the system is first pressurized, a creaking or hissing sound is normal. This noise should stop after pressurizing. Always check for leaks.
What to do if the relief valve is dripping on my Amtrol BoilerMate RTR Water Heater?
If the relief valve on your Amtrol Water Heater is dripping or opening, here are some potential causes: * There might not be a thermal expansion tank installed. Install the correct Therm-X-Trol® or equivalent thermal expansion tank. * The thermal expansion tank might be set up incorrectly. Make sure the precharge air pressure matches the static water pressure. * The city water pressure could be too high. If it's over 80psi, install a Pressure Reducing Valve (PRV). * The system might be overheating. Find out what's causing the over-temperature condition and fix it. * The relief valve itself could be faulty. Replace the relief valve.
Why is the water from my Amtrol BoilerMate RTR discolored?
If the water from your Amtrol Water Heater faucet is discolored, it could be due to: * Poor water quality. Have the water tested for contaminants. Common issues include blue/green water (copper discoloration due to low pH), black staining/sulfur odor (hydrogen sulfide), white deposits (hard water), and red staining (high iron levels). * Sediment or suspended particles. Install a sediment filter and purge the unit more often to prevent future problems.
Why won't the circulator or zone valve operate on my Amtrol Water Heater?
If the circulator or zone valve isn't working when your Amtrol Water Heater calls for hot water, here are some things to check: * Incorrect or loose wiring. Check the connections against the wiring diagrams in this manual. * The Pre Purge (PRE) setting is too high. The PRE setting delays circulator startup, which isn't usually needed in residential applications. Reduce PRE or set it to 0 if the problem continues. * A fuse in the Smart Control™ is blown. Remove the 4 screws inside the Smart Control™ wiring box and replace the glass fuse(s) with those of the same rating. * The circulator pump is faulty. Repair or replace the pump.
