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.
