6.3 Domestic Combi System
(((OPTIONAL on Ti150 and Ti200 Only)))
"The Trinity Combi is designed for installations where there is a limited DHW demand, such as smaller apartments and condos. In
applications where there is a greater DHW demand we recommend the use of our heating model boiler in conjunction with an Indirect
Water Heater."
The Combi has all the
features of the standard heating version plus;
External Combi Manifold, diverting valve,
plate heat exchanger & flow switch.
Note:
The installer is required to install the pump
flange (included in Combi kit) onto the boiler
return pipe prior to installing the boiler; the
bolts must be inserted into the flange prior to
installing the flange.
COMBI Sequence of operation
When water flow greater than .5 GPM passes through
the flow switch, it closes a contact to terminals A-C on
the Sentry 2100 controller. The boiler is immediately
energized (if not already on), the 3-way diverting valve
moves to the domestic hot water position “A”, and the
circulator is energized. Hot water is circulated through
the plate heat exchanger. The flame is modulated to
maintain the “LO” setting on the Sentry control. The
Sentry uses the boiler thermister to read the
temperature of the boiler water. Space heating is not
provided during a call for domestic.
