INTRODUCTION

HTW-61-EW001-B is a Noise-Free room climate controller application for water installations with fan coils. It is designed as a stand-alone device to operate the fan coil
unit of a zone and includes a set of functions for zone occupancy and window position-based climate control. A high level of comfort and appropriate climate control to ensure maximum energy savings are thus provided.

The device is a compact unit that includes a large backlit display screen, a built-in temperature sensor, pushbuttons on the front panel, and inputs and outputs built on a split remote relay module for room control.
This split thermostat application includes two parts:Hotowell-HTW-61-EW001-B-Room-Controller-THERMOSTAT-Instruction-Data-Sheet-FIG-3

  1. Manual operation display part: HTW-61-EW001-B
  2. Remote relay module part: HTW-61-EW001-RM

These two parts are communicated via 4-wire connections:

  • GND
  • 12V
  • TXD
  • RXD

It provides a totally Noise-Free application due to its remoted relay module.

  2. Analog, ambient temperature external sensor
  3. Temperature sensor, built in on device front panel

Outputs:

  • 3 Relays, fan coil speed (I,II,III)
  • 1 Relay, chilled water valve
  • 1 Auxiliary relay (hot water valve on 4 pipe systems / lighting on 2 pipe systems)
  • 1 Auxiliary relay for lamp

Product description

The split controller Noise-Free application is designed for room climate control at hotels, offices and homes with water and fan coil installations. The device includes all the necessary inputs and outputs to operate a 2 pipe or a 4 pipe system; control over one or two on/off valves and a 3 speed fan coil is provided to maintain room or zone temperature to user requirements.

The device includes a built in temperature sensor on its front panel for room temperature measurement, and features an advanced control algorithm for fan coil speed and valve position control. Two digital inputs are also provided, one to detect zone occupancy from a keycard switch contact-used in hotels to indicate that the room is occupiedand another one to connect to a window contact-used to temporarily disconnect operation when the window is open. The keycard switch input may alternatively be configured to control zone lighting on 2 pipe systems. In this case, one of the valve outputs converts to lighting control output.

The device includes a simple configuration menu that allows configuring up to 28 parameters. The unit can thus be adapted to the requirements of each installation.
More importantly, the device is designed with a remote relay module, in order to provide a totally Noise-Free application.

Configuration Parameters

Special Note

  1. During power-off status, push and hold “Fan” and “+” buttons together for 6s to entry the configuration parameter setting;
  2. There are two lighting output.
    • lighting 1:when P10 configured as 2P,the Aux is working as a courtesy lighting;
    • Lighting 2: Lamp output(terminals 14-15) associated with window contact input.

Notes
 

 

1)

Anti-humidity algorithm:when the key card pulled out,the device automatically switch to work at set-point 24 degrees for a period of time every confirgured mintues depending on the configuration of P29
2) Priority parameter on P8
 

 

3)

The internal/external temperature sensor is selected by placing jumper J1 on position IN or OUT; The IN & OUT dual sensor mode could be configured by removing the jumper.
 

4)

If P9 is confirgured as ALL, defaulting display SET, and display TEP by pushing and holding “+”&”-” buttons together, 6s later return to SET display.
 

5)

When this parameter is programmed as ON, if the parameter number 5 is setted up as ECO and the room is unoccupied, the equipment will start in ECO mode.
 

 

6)

If it shows 0 seconds, the auxiliary output will remain active while the key-card input is active and it will be disconnected when the key-card input is switched off and exceed the settedtime in parameter number 6.
