Things To Consider

Cross-Reference Alternatives

Ranco product's model numbers generally cross individual reference to the equivalent Honeywell, Johnson Controls, White-Rodgers & Robertshaw MPNs (manufacturer's part numbers). So, if you're looking for thermostats, valves, controls & accessories that are either out of stock or obsolete, chances are Raptor Supplies has the alternate product available.

Shipping

These Ranco products are generally small in size and require compact packaging. They are suitable for courier shipment and not air freight.

About Ranco

Ranco line voltage thermostats provide on / off control for air conditioning, refrigeration and commercial heating. These Ranco thermostats feature two programmable stages for cooling & heating and an LCD screen for indicating relay status & temperature readings. They are capable of sensing temperatures ranging from -30 to 220 degrees F. Ranco ice maker controls maintain the ice thickness in refrigerated cabinets, ice builders and soft drink vending machines. These controls feature bulb & capillary sensors for auto turn-off & high separation resolution.

Frequently Asked Questions

How to set up a Ranco thermostat?

  • Ranco's ETC line of thermostats / temperature controls can be set using the set, up & down buttons on the unit after powering them On & pressing the set button. Users should first select their required temperature unit (degree F or C) by pressing the set button again.
  • After returning to the main menu, "S1" icon will appear on the display, press the up or down arrow keys to increase or decrease the set-point temperature. Press the set key again to return to the main menu.
  • Users will see the "DIF 1" icon blinking in the display. Press the arrow keys to set the temperature differential (temperature range where the thermostat would operate in the heating / cooling mode). The differential temperature in the heating mode is set lower than the setpoint temperature, whereas it is set higher than the setpoint in cooling mode. Press the Set key again.
  • Either "C1" or "H1" will blink in the display window to program the cooling & heating settings. Press the set key to lock the programming choices and finish the set-up of a Ranco thermostat.

What do different error codes mean in Ranco temperature controls?

E1 error code appears in the controller when the up or down arrow key is pressed without going to the programming mode, whereas the E2 error indicates that the control setting is not stored properly in the memory. EP error code denotes an open / shorted probe or out of range temperature sensing and the EE error code shows corrupt EEPROM data. CL code appears if the user has entered the calibration mode.
