Introduction
The VSMR(Variable-Speed
Module) is a self-contained
package for radiant floor heating.
It can provide floor warming or
room heating for an entire
building or anywhere that
requires extra comfort through
radiant floor heating. It is
suitable for new construction or
for renovations – commercial,
industrial, agricultural or
residential. The injection pump
provides the precise amount of
hot water needed based upon
heating load.
A loop pump, heat exchanger,
variable speed injection pump,
and electronic controls are
contained in an attractive cabinet
that can be directly connected to
A Rinnai tankless water heater.
Each unit has the necessary
valves required for servicing the
tankless water heater as well as
a connection for an expansion
tank. The unit comes pre-
assembled to save time and
simplify installation.

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 VSMRincludes 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.

Start up
Ensure all plumbing connections are complete.
Purge all air from the domestic and hydronic
system. Opening a DHW fixture will eliminate
air on the domestic side of the system.
The closed loop side of the system can be filled
by closing the isolation valve located between
the two drain valves . Subsequently fill the
system through the drain valve on the supply
side to closed loop system. Open the drain
valve on the return side of the system to purge
air and to return liquid to the filling vessel or to
drain.
The expansion tank should be charged as per
expansion tank installation instructions. An
isolation valve is located on the line for
connection of expansion tank. It can be used if
if necessary.
When the closed loop system is filled, close
both drain valves used to fill the system and
open the isolation valve located between them.
The tankless water heater will operate during a
heat call cycle and for domestic hot water.
The VSMR is self calbrating. The control
automatically determines supply temperature.
LED Diagnostics are available for fine-tuning
the system. See Attached Table.
Troubleshooting
No heat -- check the following:
• Check the tankless water heater inlet
screen. Particulate may be restricting water
flow through the heater
• all required valves are fully open.
• power available
• pump is running (a screwdriver held to the
pump can work like a stethoscope)
Noisy Pump
• Repeat purge procedure
Heat distribution
• The VSMR will provide heated water to the
loop system at the lowest possible
temperature to ensure efficient operation.
• The floor surface will feel neutral as a result
of operation in an optimal range. Loop
supply temperature is not an indicator for
comfort. The VSMR will automatically
determine the appropriate supply
temperature and deliver even heating to the
loop.
