8. TROUBLE SHOOTING CHECKLIST
PROBLEM
1. No hot water at faucet.
2. Insufficient or runs out of
hot water at faucet.
3. Water at faucet too hot.
4. Boiler cycles more than 5
times per day in summer.
Boiler runs for longer
Periods of time .
CAUSE
1.Boiler does not operate.
2.Circulator does not operate.
3.Improper BOILER MATE™
setting or calibration.
4.Zone valve does not open.
5.Electrical problems (relay, wiring,
fuse, low voltage, brown-outs, etc.)
6.BOILER MATE™ scale
build-up.
7.Clogged filter (if used) or clogged
strainer in steam boiler systems.
1.BOILER MATE™
temperature setting too low.
2.Undersized boiler with no
priority to domestic hot water.
3.Peak use of hot water is greater
than BOILER MATE™ storage.
4.BOILER MATE™ scale
build-up.
5.Faulty BOILER MATE™
temperature control.
1.BOILER MATE™ temperature is
set too high.
2.Improper system plumbing.
3.Improper system wiring.
4.Probe out of thermostat well.
1.Excessive demand.
2.Damaged or broken BOILER MATE™
temperature control.
3.Boiler hi-limit set too low.
4.BOILER MATE™ scale build-up.

SOLUTION
1.a. Press reset button on boiler.
b.Check main cut-off switch.
c. Check fuse.
2.a. Check power supply.
b.Check shaft coupling.
c. Check impeller for locking.
3.Set BOILER MATE™ temperature to
a higher setting. Call boiler service.
4.Check power supply.
5.a. Check fuse and replace.
b.Check circuit breaker and
reset (if applicable).
c. Check power supply.
d.Low voltage or brown-out conditions
can make the boiler control inoperative;
engage the boiler reset button.
6.If boiler, circulator, and BOILER MATE™
temperature controls are operating
satisfactorily, the BOILER MATE™ coil
may have scale coating. Remove coil and
clean or keep coil in tank and treat with
a phosphoric acid product (e.g. NuCalgon -
1-800-554-5499) (Refer to page 20)
7.Clean and replace filter.
1.Set BOILER MATE™
temperature control to a higher setting.
2.Rewire for priority.
3.Determine peak usage and compare tank
volume.
4.Clean coil according to instructions.
5.Replace control.
1.Lower BOILER MATE™
temperature.
2.Compare plumbing to installation guide.
3.Compare wiring to installation guide.
4.Check to make sure Probe is properly inserted,
see Figure 2 Page 8.
1.Reduce demand or consider larger
BOILER MATE™.
2.Replace BOILER MATE™
temperature control.
3.Increase boiler hi-limit.
4.Clean coil according to instructions.
