LOW TEMPERATURE SENSOR, P/N H2000.36 – (WARNING: When working with
electrical circuits, use caution to avoid electrical shock)
– This sensor can be wired in
the home heat thermostat circuit to prevent the pump on the heater from running when the
water in the wood heater is not hot. The sensor has set of contacts that close when the
water rises to 110’F and open when the water drops to 90’f.
WATER PUMP RELAY, P/N H2000.52 - (WARNING: When working with electrical
circuits, use caution to avoid electrical shock)
– This is Honeywell DPDT relay with a
24 volt coil. Terminal 4 and 6 (normally open contacts) are used to turn on the water pump.
Control voltage (24volts) connected at terminals 7 and 8 routed through a home thermostat
energizes the relay.
WATER PUMP FOR HEATING SYSTEM, Taco 009 pump P/N H502.00 –
(
WARNING:
When working with electrical circuits, use caution to avoid electrical shock) - with
bronze body. If the pump will not run, first unplug the power cord then check the water
pump relay. The relay can be bypassed by disconnecting the wire terminal 6 and the
connecting to terminal 5 (terminals 4 to 5 is normally closed) remove the thermostat wire
from terminal 8, and plug the power cord back in. This should supply 115vac directly to the
pump. If the pump will still not run, unplug the power cord. Remove the four bolts holding
the pump to the pump housing. Remove the cartridge from the pump. Spin the impeller, if it
will not spin, replace the cartridge. If the impeller will spin, it may have been temporarily
stuck (reassemble and try again) or the problem is the electrical winding or capacitor. Use
an ohm meter to check the winding and capacitor. If the capacitor is defective, replace it. If
the electrical winding is defective, replace the complete pump.
