New Horizon BioMass NextGen 25, Owner'S Manual

Page: 6 / 19

For ease of operation, the BioMass is equipped with an RK2001UA-D controller, which
is located on the top of the boiler and clearly visible and accessible from the front of the
boiler.
Function of the Controller:
1. Reach operation temperature (pre-set on dial) by operating variable speed
blower
2. Operate water circulating pump in preprogrammed setting
3. React with room thermostat (advance setting)
4. Enable oil boiler when wood burner is operating or disable oil boiler when wood
burns out
In case of excessive water temperature (creeping over 195°F), overheating should be
prevented by a safety thermostat (aqua stat), which should activate so-called damp
zone (in garage or in basement to relieve excess heat). Controller is also able to
automatically shut down operation of blower in a case of system failure (will leave pump
operating).
