, with over 20 years of technological leadership in Pool & Spa Chemical Control Systems
congratulates you on your selection of the MiniWarden Chemical Controller. MiniWarden is a water
chemistry control system with capabilities to control the pH and sanitizer on a pool, spa, fountain or any
other similar body of water. Using ORP (oxidation reduction potential) technology the control of sanitizer
takes into account the effects of pH and a pH lockout feature is also included for high pH values.
Supporting both 110 and 240 VAC, the MiniWarden will control chemical feed equipment using relays to
keep the pool or spa water in balance. Water measurements are taken continuously while MiniWarden's
internal relay programing determines if chemical adjustments are needed. MiniWarden also contains a
selection for the sanitizer relay to be dry-contact which can be used for salt water chlorine generators
and solenoid valves that are controlled with a different voltage or a simple switch.
MiniWarden Plus
When adding the PW-Plus communication module, the software feature set will also be updated. Where
there are differences that will be pointed out.
System Components
�
CONTROLLER
: MiniWarden is a microprocessor based, modular automation system that is
capable of continuous monitoring locally onsite or remotely offsite.
�
INTERFACE
: MiniWarden uses a 16-button built in keypad, and an easy to read 80 character
liquid crystal display. The display’s internal back-light provides controller viewing in pool rooms with
low light conditions.
�
MEMORY
: MiniWarden is designed with nonvolatile memory which preserves all internal
programming in case of power loss. Internal memory is preserved for up to 10 years without having
power applied.
�
RELAYS
: MiniWarden includes 2 output relays for the control of pH and sanitizer.
�
SENSORS
: ORP, pH, Temperature, flow and optional free chlorine sensors.
�
VOLTAGE
:
Requires 120VAC input voltage in North America and 240VAC input voltage in Europe.
�
SECURITY
: MiniWarden is designed with a lockable enclosure and provides up to four levels of
password security protection (Admin, Tech, Service and Guest) for both local onsite and remote
offsite interaction with the controller with 4 passwords.
�
COMMUNICATION
: MiniWarden can connect to the Internet for direct monitoring, setup, and data
interface by adding the PW-Plus communication module which adds WIFI and Ethernet.
�
DATA
: MiniWarden will record up to 8192 lines of data with the built in internal memory. There is no
limit when adding the PW-Plus communication device
�
OVERFEED PROTECTION
: MiniWarden is designed with overfeed protection. Standard Overfeed
limits the amount of time a relay can turn on feed equipment in a 24-Hour period. Also includes a
setpoint overfeed limit that can be used to prevent chemicals from being fed onto the floor of the
equipment room by damaged feed tubes.
�
PROPORTIONAL/SPAN CONTROL
: Proportionally reduces the on-time as the measurement gets
closer to the set-point to prevent overshoot.
�
E-MAIL ALERTS
: The data server provides support for 4 email addresses and 4 phone numbers for
texts.
�
PRINTING
: Bluetooth printing when adding the PW-Plus communication module.
�
SOFTWARE UPDATING
: PW-Plus supports immediate software updating over the Internet.
