Mounting
The VSMR may be mounted in a mechanical
room or basement wall or in a closet. Ensure
the Rinnai tankless water heater is installed
according to Rinnai Installation Instructions.
The VSMR is designed to be surface mounted
and directly connected to the Rinnai water
heater using the union connections provided
For surface mounting, use anchors suitable
for the wall surface (concrete, drywall or wood
screws). The cabinet should be screwed using
the flanges on the top and bottom of the
cabinet.
Piping Layout
Each VSMR has one zone pump. Note that
some custom systems may use multiple loop
actuators. Actuator end switches may be used
to provide heating. Ensure all end switches are
wired in parallel to the terminals marked
thermostat.
Contact Ecologix for assistance with your
radiant heating system design.
Plumbing Connections
All connections to the VSM are sweat copper
and may be adapted to crimp PEX,
compression PEX or NPT. Many options are
available for circuiting the in-floor loop layout
including remote manifolds.
Electrical Connections
Plug the electrical cord into a standard
120VAC/60Hz/1Ph grounded outlet. This
device draws less than 3 amps and does not
need to be on a separate circuit. The cord can
be removed and the unit hard wired by a
qualified electrician. Follow all local electrical
codes.
The VSMRincludes a pre-wired 24VAC
power supply for the controls. Connect your
heat only thermostat to the low voltage terminal
strip provided inside the cabinet.
For complex zoning ensure the room
thermostats used have their own independent
24VAC source. 24 VAC connections provided
inside the cabinet must be isolated from this
foreign power supply. Using 24V sources that
are not in Phase will result in an electrical
failure. Contact Ecologix for assistance with
your radiant floor heating design.
To install the optional outdoor sensor, remove
the factory installed jumper/resistor The
outdoor sensor is not polarity sensitive and is
connected to TA4 and TB4. Call Ecologix for
details.
