PROBLEM	CAUSE	SOLUTION
No hot water at	ECO on thermostat tripped	Determine if ECO trip is a result of excessive solar heat or
faucet		electric element. Correct or replace as necessary. Depress red
		“RESET” button on thermostat
	Improper thermostat setting	Adjust tank thermostat to appropriate setting
	or calibration	See Section VII
	Circulator does not pump	Check electrical connections
	fluid through solar collector	Check that proper valves are open
		Check that system is bled
		Replace as necessary
	Electrical problem (Control,	Check fuse and replace
	wiring, etc.)
		Check circuit breaker and reset (if applicable)
		Check power supply
	Scale build-up	If solar controller, collectors, circulator, and tank are operating
		satisfactorily, coil may have scale coating. See Section VIII:
		Maintenance
	Clogged cold water filter	Clean or replace filter or strainer
Water at faucet	Thermostat set too high	Adjust thermostat setting. See Section VII
too hot
	Improper system plumbing	Compare plumbing to Section V
	Improper system wiring	Compare wiring to Section VI
	Mixing Device temperature	Adjust Mixing Device setting. Refer to Mixing Device
	set too high	instructions.
Insufficient hot	Thermostat setting too low	Adjust thermostat to higher setting. See Section VII
water	Undersized solar collectors	Review calculations for proper collector surface area,
		orientation and available sunlight
	Faulty solar sensor or solar	Check connections, power and sensor resistance. Replace as
	controller	necessary.
	Peak use of hot water is	Determine peak usage and compare to tank capacity
	greater than tank storage
	capacity
	Circulator does not pump	Check electrical connections
	fluid	Check that proper valves are open
		Check that system is bled
		Replace as necessary
	Faulty tank thermostat	Replace thermostat
