ENGO CONTROLS EPC11W is a pump controller designed for central heating or hot water tank systems. It can be used to automatically turn on/off the pump based on temperature sensors, acting as a safety thermostat. It features an anti-stop function to prevent lime scale buildup and frost protection to keep the pump running when temperatures drop below 5°C. The device has an LCD display, adjustable temperature settings, and an alarm for high temperatures or sensor issues. It complies with EU regulations for EMC and RoHS.

Introduction
Controller is designed to control water pump in central heating
system or pump of the hot water tank. It can be used also as a safety
thermostat. Controller will turn on or turn o the pump depends
on the sensor temperatures. Pump is running after exceeding the
setpoint temperature „C” set by user and it will stop after exceeding
setpoint temperature „U”.
Product Compliance
This product complies with the essential requirements and other
relevant provisions of the following EU Directives: EMC 2014/30/EU,
RoHS 2011/65/EU.
Safety Information
Use in accordance to national and EU regulations. Use the device as
intended, keeping it in dry condition. Product for indoor use only.
Installation must be carried out by a qualied person in accordance
to national and EU regulations.
Before carrying out any activities related to the power supply (con-
necting wires, device installing etc.), make sure that main power is
not connected to the controller! Incorrect wiring connections may
cause device damage.

Principle of operation
Wiring diagrams - examples Controller operation
Setpoint temperature of the pump start can be changed by pres-
sing button (menu option). On the display appears ashing
„C” letter. At this point „C” setpoint temperature can be changed
with or buttons. After few seconds controller will go
itself into operating mode and display the current temperature.
Setpoint temperature of the pump stop can be changed by pressing
twice button (menu option). „U” parameter is the next parameter
after „C”. On the display appears ashing „U” letter. At this point „U”
setpoint temperature can be changed with or buttons. After
few seconds controller will go itself into operating mode and display
the current temperature.
C – activation temperature of the CH pump above the set value
(setting range 5-75°C).
U – maximum HW reservoir temperature
(deactivates the HW pump above the set value, setting range 10-80°C).
Manual mode
This function allows to check if connected pump is working correc-
tly. The pump will be turned on after pressing buttons and .
Pressing these buttons again will turn o the pump.
Histeresis
This is the dierence between setpoint temperature of the pump start
and setpoint temperature of the pump stop. Controller has a constant
hysteresis of 2°C. For example:
1. When „C” parameter is set to 30°C, then pump will turn on after
exceeding 30°C and turn o when temperature will drop to 28°C.
2. When „U” parameter is set to 50°C, then pump will turn o after
exceeding 50°C and turn on when temperature will drop to 48°C.

2. HOT WATER PUMP CONTROL
OR WORK AS A SAFETY THERMOSTAT
Additional functions
Controller has an „anti-stop” function which protects pump against
lime scale when there is no heating season. Pump is turned on every
14 days for 15 seconds.
An additional protection is the frost protection function, which runs
pump permanently when temperature on the sensor drops below
5°C.
230 V AC
Hot Water
NOTE! The „U” parameter should be set to the maximum
value. Pump will be turned on when temperature sensor exceed
the value of „C” parameter.
NOTE! The „C” parameter should be set to the minimum
value. Pump will be turned o when temperature sensor exceed
the value of „U” parameter.

Alarm
The controller is equipped with an acoustic alarm signaling:

If the E1 or E2 error is displayed, the CH pump works all the time until
the fault is removed.
