Delta-T Variable Speed, ECM High-Efficiency Circulator
DESCRIPTION:
The 00e
™
series VT2218 circulator is a temperature sensing, self-adjusting, variable speed
wet rotor circulator with an ECM, permanent magnet motor. Operating modes include
Delta-T, constant speed, set point heat, set point cool, and boiler protection. Its high
efficiency motor reduces power consumption by up to 85% compared to equivalent AC
permanent split capacitor circulators.
APPLICATION:
• Maximum operating pressure: 125 psi (862 kPa)
• Minimum water temperature: 36ºF (2ºC)
• Maximum water temperature: 230°F (110ºC)
• Electrical specifications:
Voltage: 110-120V, 50/60 Hz, single phase
Maximum operating power: 58W
Maximum amp rating: 0.67
• Equipped with a cast iron casing and should be used for closed loop systems only.
• Taco circulator pumps are for indoor use only – employer uniquement a l’interieur.
• Acceptable for use with water or maximum of 50% water/glycol solution.
FEATURES:
• 5 operating modes:
- Delta-T - variable speed, maintains constant ∆T, provides exact GPM flow required
- Constant Speed - 4 fixed speeds, maintains constant flow for zoning
- Set Point Heat - variable speed with boiler protection option, decreases speed on temperature rise
- Set Point Cool - variable speed, increases speed on temperature rise
- Boiler Protection - protects boiler from low return temperature and flue gas condensation
• Illuminated LCD displays:
- Operating mode, speed or temperature setting, watts, gpm, supply temperature, return temperature, and
error code diagnostics.
• Use with a Taco ZVC Zone Valve Control or SR Switching Relay for ON/OFF operation.
• Integral Flow Check (IFC) is included in carton. Simply press into discharge flange if required.
• Nut capture feature on flanges for easier fit up.
• Whisper quiet operation.
• BIO Barrier
®
protects the pump from system contaminants.
•
SureStart
automatic unblocking mode.
• Optional, 2-way flange model available to reduce SKU’s and provide universal fit-up to any flange position.
INSTALLATION:
WARNING: Do not use in swimming pool or spa areas. Pump has not been investigated for these applications.
AVERTISSEMENT: Ne pas utiliser dans une piscine ou un spa. La pompe n'a pas été étudiée pour ces applications.
CAUTION: The addition of petroleum based fluids or certain chemical additives to systems using TACO equipment voids the
warranty. Consult factory for fluid compatibility.
ATTENTION: L'ajout de liquides à base de pétrole ou de certains additifs chimiques à des systèmes utilisant un équipement TACO
annule la garantie. Consultez le fabricant pour connaître la compatibilité de liquides.
CAUTION: Installations at elevations over 5000 feet must have higher fill pressure of 20 psi minimum to prevent pump cavitation
and flashing. Premature failure may result. Adjust expansion tank pressure to equal fill pressure. A larger size expansion tank may
be required.
ATTENTION: Des installations à des altitudes de plus de 1600 mètres doivent présenter une pression de remplissage plus élevée
de 20 psi au minimum afin d'éviter toute cavitation ou flashing de la pompe. Une défaillance prématurée peut en résulter. Réglez
la pression du réservoir d'expansion de façon qu'elle soit égale à la pression de remplissage. Un réservoir d'expansion d'une taille
supérieure peut être nécessaire.
