3 GENERAL
The 800 Series includes five HBL8x (30”) and two HBN8x (27”) built-
in wall ovens. Models have thermal oven cavities and/or Euro-
convection (convection with ring element) cavities. The lineup
includes two field-assembled combination models with either a 120V
Solo Microwave Oven or a 240V Microwave Speed Oven.
Available colors are bright stainless, black stainless, or black
porcelain, and all models feature VFD red and white displays with
touch controls. The wall ovens are designed to be installed flush with
cabinetry.
The control panel and door skins on the stainless models are made of
grade 439 stainless steel, which is magnetic.
3.1 Recap of Functional/Technical Changes
 Cooling fan: now operates with a variable speed protocol.
Hall effect sensor has been eliminated, and thermal limiter
(HTC) has been added.
 Power supply: now located on the control module (relay
board) rather than as a separate component.
 User interface: no longer separate user interface software;
the control module drives the user interface. VFD-based
display with capacitive touch panel managed by a separate
touch control module (TCM).
 Daughter board (double ovens only): populated with relays to
operate the lower oven.
 Ventilation: air flows up through each door, then back out
over each door as air exits the appliance; some air is pulled
into the unit at the lower vent area under the appliance.
 Lighting: Soft lighting is standard on all models. Double oven
lighting is not independent – lights operate concurrently.
 Temperature control: now a two-point control for all modes
rather than a PID control for all modes.
 Hinges: All models include soft-close doors.
