An example: Your supply temperature is 140 degrees F and your target return temperature is 100
degrees F. (100 - 50) / 10 = 5 and 100 + 5 = 105. Referring to the chart yields a TMV dial
setting just below 2.
Timer for the RHP-1
and RHP-2 Models
The TMV has six settings which are changed by turning the knob under the square cover on top of the
TMV on the RHP 1, the RHP-2 does not have a cover. Remove the cover by prising against the small
tab on either side. In order to adjust the TMV to the proper setting, determine the supply temperature
to the RHP and the desired return temperature. [Some boilers require a minimum return temperature
to protect against flue gas condensation, consult your boiler provider if applicable] Subtract 50 from
the return temperature and divide by 10. Add this number to the return temperature to determine the
target temperature as seen on page 18 (RHP-1) and page 20 (RHP-2)
Start Up
1. Set thermostat(s) 5 to 10 degrees above actual room temperature.
2. If a floor sensor is used make sure the minimum setting (if used) is at least
5 to 10 degrees higher than the actual floor temperature.
3. If you are using the auxilary contacts to bring on the heat source, make sure
they are connected.
4. Plug power cord into a 110V outlet.
5. Observe the panel to ensure it follows the proper sequence of operation.
6. After the system temperature stabilizes, verify mixed fluid temperature
is within a few degrees of the desired set point by checking with a temperature
gauge. If the temperature is off, re-adjust the 3 way thermostatic valve.
The integral timer’s purpose is to circulate water for a short period each day within the system.
If you are employing an open system (sharing the heat source with domestic uses) this prevents
any “stale” water from accumulating in the pipes during the summer period. The timer will activate the
system for 15 minutes every 24 hours. You should leave the panel turned on with the thermostat
turned down even in the summer to allow the timer to activate this circulation. If you are operating
a closed system, you may turn the panel off in summer or even disconnect the power cord.
